a friend of my friend was inches away from getting hit by a car the other day. i wasn't there but my friend told me how this friend was acting perfectly fine right after but she started crying hysterically at same night, to the point where she finally fainted. then she woke up not remembering her roomates, including my friend, and was saying how she sees all these people in her room when there were only 2 people there. she couldnt recall what had happened earlier and she went straight back to sleep. a couple hours later she woke up again, sat straight up and said "im confused" to my friend and laughed. my friend freaked out and offered to take her to the ER but she said she was fine. the next day she woke up normal again but couldnt remember what had happened the night before. she could remember the car incident thought, what recreation is this? why and how?
