my cousin who is 21 now had a similar experience. he started getting interested in the bible and church and was just starting out. he was playing semi pro soccer and they had lost a game and he was cursing God for it. that night when he went to bed he said he was woken up by a really eerie feeling. he opened his eyes and couldnt move his body an inch. he saw a dark black figure walking around his room looking around. he said the figure almost acted as if he owned the place. my cousin tried to speak but couldnt. he said in an instant the figure was on top of him. he felt a pressure on his bed and chest and he said he couldnt move or speak or anything. the figure laughed and then disappeared. pretty freaky stuff
