After that day I been having some strange , I dont know how to call it, but sometimes when I go sleep I feel that I cant open my eyes, or move, or scream or do anything. I feel that my body is been touch, I know it sounds crazy or maybe I need a psycology, but the true is that after that day I dont know nothing anymore.((NUFORC Note: Witness indicates that the date of the incident is approximate.
