When i was 14 i had an expierience where in the woods i was struck by a sudden urge to lay down and a bush tranmoehed into a demon looking guy, grey skin, glasses, and wearing a suit that had age and burn holes in it. He struck me mute and paralyzed as he spoke, only with pictures instead of words showing me many events leading up to a riot looking scene with ruins of a city around me. He then spoke the only words he ever spoke. No matter how hard you try you will not die. Then as he dissappeared i was able to stand and hours had passed and it was daylight. Sience then my life has fallen to pieces time and again as the events that he showed me come to pass from time to time. People say they can feel a prescence around me and once a gf of mine on lsd described him in detail and i had never spoken to anyone about it. I know i ran into something but i dont know what. I feel cursed but not possesed per se. Anyone wanna offer me any information they think may be relevant?
Your experience strongly resembles the shamanic state of consciousness. In a healing ceremony, the shaman rattles and dances to the beat of drums and then lays down on the ground to pass into the earth for his journey. On his journey, he seeks help from spirit to recover whatever the patient needs to recover. Once found, he secures it and brings it back to his patient changing into his ordinary state of consciousness. Sounds like you were tricked by something into doing the same thing, but in reverse. The entity found a way to put you into an altered state so you laid down on the ground and it performed some sort of spiritual transference to you.
The connection between spiritual entities and living humans is certainly a topic for discussion. No answer is entirely right or wrong. It is your decision on how to approach the problem. I can only suggest that you research shamanism and perhaps find a way to return into the earth and discard what is attached to you. Perhaps a spirit guide can help you in this matter if this suggestion appears to be an appropriate method for your path.
