This is a potentially tricky situation. Being a trained psychotherapist who is interested in this subject matter, I have to caution you - no matter what direction you choose to go to for support or to seek out an opinion on your experiences, there is always going to be a certain degree of "reframing" going on. And this simply means that those who consider themselves experts on anomalous experiences will file them away according to their main frameworks of interpretation. For example: A Jungian psychologist might see them as Transpersonal in orientation, a Psychiatrist as potentially psychotic delusions, a shaman as initiation episodes, a Hindu Yogi as "siddhi", a Dr. Stanislov Grof as experiences of non-material realms, and a Budd Hopkins type as precursors or indications of abduction-related phenemenon. The path you chose to take is an important one, for your experiences can only be validated ultimately by you. I'd say there's a few steps one might consider - First, do your best to rule out that there isn't any neurological disorder -schedule an appointment and avoid describing the backstory to your present experiences. Reveal your concern in the framework of "unexplained" phenemenon, but unless you want to be on the high road to neuroleptics, be frugal with the details. I say this only upon the assumption that you are not a potentially dual-diagnosis candidate, i.e. experiencing said phenemenon with the addition of depressive episodes, substantial mood swings or changes in energy, and or delusions of reference and hearing voices. If your psychological state happens to fit with dual symptomology, well, do consider quite seriously the option of seeing a psychiatrist. Additionally, consider the option of seeing a psychotherapist. Take the time to learn about yourself and the implications of your family of origin as well as subconscious and higher conscious activity. Do this only if you feel comfortable devoting yourself to such an enterprise, because it does demand a great deal of energy and fortitude. Therapy may stand to provide you with a clearer picture of why these things may be happening. Practically, maintain a healthy amount of skepticism and continue to investigate the phenomenon, but be sure to involve a system of checks and balances - i.e. bounce some of your findings/ideas/conclusions off someone close to you who is level headed and whom is someone you can trust. This forum is a good expression of that, but there is a considerable amount of "reframing" you will face on this board.
As for validation that is something you will find in yourself and in maybe from those who love, work and see you in da flesh. Also, in your inner life where you are known by your "maker" if you accept that or by your own "mind." Truly, nobody on a forum or even on the "street" can know your inner life or who you truly are. I hope you find peace and I hope you find truth.
