In the past (and perhaps still, in other cultures) men spontaneously experienced "contact" with gods or God, the divine - more generally, spirits, the dead/ ghosts, and many other supernatural/ paranormal forms of interaction such as with remote persons or animals.
These also include sensory/ perceptual experiences such as the seeing of spiritual visions, or hearing voices and having conversations
But here-and-now it seems that adult and healthy (or healthy-ish) modern Men - and I count myself as pretty typical in this respect - do Not spontaneously have such experiences; nor can we have such experiences in alert, healthy, and clear consciousness; no matter how we strive.
"Contact" of this sort only happens spontaneously to modern Men in states of lowered consciousness; such as dreaming sleep, trance, intoxication; or when there is brain dysfunction in psychosis (including with brain diseases, such as dementias).
To my mind, the difficulty or impossibility of having these supernatural/ paranormal experiences of contact and interaction, points to the conclusion that the old sensory/ perceptual experiences (while they may lead to good) are ultimately retrograde, "atavistic", and often motivated by a nostalgia and desire to revert to an earlier (less conscious, more automatic, less free) phase of the development of consciousness (which we may recall from early childhood, or have imaginatively experienced).
But given the mundane and alienated nature of typical modern consciousness, and more importantly (indeed vitally) the necessity for each of us to receive personal guidance from the Holy Ghost in particular - given these needs, we must develop other ways of establishing some kind of experienced-interaction or "contact" with spirit Beings.
Indeed, I have often said that this kind of interaction is the basis for metaphysical reflection on the fundamental nature of reality. It is the basis of that "intuition" upon which everything depends - and which I have variously called "direct knowing", or sometimes "heart thinking" or "primary thinking".
The point is How To Do It?
In my experience, I think this contact works by an awareness of such contact while actually speaking, writing, or thinking.
It is a "direct" form of knowing, because (unlike the past and other cultures) there is no sensory aspect.
What it is like is a deep and simple sense of affirmation or rejection, support or opposition, yes or no.
Such a "feeling" is indeed the deepest awareness of which I am capable.
This does not mean the experience is infallible, but that it is the best I can do - here and now.
Because the experience is deep, it is not reached as a result of inference from other kinds of evidence, nor does the awareness come with "proof" of itself - although naturally evidences, proofs, excuses and the like can be derived or contrived secondarily - after the guidance.
Since this mortal life is mostly about what we ought to try to do, here and now - in these particular circumstances - the experience-of-itself suffices.
As an example; this is how I have developed my fundamental theological convictions. For instance, I needed to decide whether "God" was single or a dyad: more exactly I wanted to know whether God meant a Heavenly Mother, as well as Father.
I had come across the idea of God as originally eternally-married man and woman from Mormon theology, and then later the work of William Arkle. I had felt an immediate stirring and attraction to this knowledge, an experience that proved robust to re-acquaintance.
To discover its truth, to discover whether I ought to assume such a reality; I wrote about it. Writing for myself, in a journal; candidly and without an audience.
I also talked, a little, about the idea. But it is very rare to find anyone with whom such fundamental (metaphysical) subjects can be discussed in a way that is an be both unselfconsciously confident on my part, and with sufficiently engaged and sustained attention on the other person's side.
So verbal discussion is, in practice, seldom of much value - which is why writing (or indeed speaking aloud to oneself, for those who cannot or do not write) can be so helpful.
Furthermore; I thought about the subject in solitude and quiet (i.e. I prayed, in one sense of praying) - with attention to what followed in this deep level of awareness.
To explain further: this is something done with a high level of conscious awareness; because it is necessary to have two "things" in mind simultaneously: both our question and the inner-awareness of a response from another Being.
To me, this puts a tight limit on the kind of question that can be asked - the question must be worked upon until I have it absolutely clear and simple in my mind; and as soon as I have done this, and made the decision to seek some kind of guidance or opinion, and have attained a quietly attentive and concentrated mind-set: the answer arrives immediately.
The source of this inner endorsement (or rejection) is varied, and something we can decide - or, at least, we can decide "who we are asking" to the extent that we can validly conceptualize another Being.
For instance, and most importantly, the Holy Ghost is (by my current best understanding) the ascended Jesus Christ and his spouse Mary Magdalene. If I address this understanding of the HG, then the response depends to some extent on the validity of my conception.
If instead (like mainstream traditional Christians) I regarded the Holy Ghost as the spirit aspect of the Trinity; then this might well have an effect on the shape of my question, and therefore the answer.
Indeed, if the question is "improperly addressed" then there may be no answer.
That has been my understanding of what is going on when I am seeking an answer to a question rooted in false premises, false assumptions. Nothing happens.
Then there is the problem of the source of the answer - in particular whether there might be a situation where a demon was to impersonate a spirit of Good (an angel), or the Holy Ghost?
My only answer, and I think the only real and relevant answer, is that this depends on our motivations and intentions and general stance with respect to God and divine creation.
If (for instance) we are really seeking answers for selfish purposes; or if we a really aligned with Satan and against God; then such motives and stances are bound to distort and subvert the answers we get.
The only conclusion is to strive for thorough honesty; and a vital part of honesty is to try and be as conscious as possible of our real assumptions, motives etc; and then as clear and explicit as possible in describing these to our-selves.
Can we be misled and wrong? Yes of course! There is no recipe for being right.
Should be strive to be absolutely certain, with no possibility of wrongness, doubt or change of mind? No!
In this mortal world we operate from very distorting circumstances, such that being ultimately and universally absolutely correct in all significant respects surely cannot be the most important thing from God's perspective.
What typically matters is that we personally get things sufficiently right in the situation in which we now find ourselves.
Other problems will arise, situations will change, we ourselves will change - but that is all uncertain, indeed it is (because of the agency of beings) profoundly contingent.
What we must deal with in our mortal lives occurs as some primary issue, here-and-now... And Christians will have faith* that sufficient personal capability and external guidance is always available for everybody to accomplish this adequately - albeit never "perfectly."

*Note: Will have faith, because we can be confident that God-the-creator is also our loving Father (or our parents, as I believe); who therefore has individual concern for the salvation and spiritual development of each-and-all of his children. So we-ourselves and our circumstances have-been and are-being created that way. Since this loving God is creating all the time, we know that our situation always has an attainable positive path forwards - for as long as our lives are sustained.
