I don't know alot about this but there is a sort of temple thing in Edinburgh it has 3 levels of spirits. Anyways our english teacher was telling us about it and at first I was really excited to go but when I went to sleep last night I had really bad feelings like I was getting pushed out the room of this temple then I felt like I was getting scratched and pulled. There is a girl in my class and she says she is going to try to free the level 3 spirit by mirror. I don't want to go anymore but I can't pull out what will I do ??
Also I keep seeing a large snake don't know why I see it appearing round people and slithering across floors but it isn't visible to anyone else. Does anyone know what this could be ? Please help me I don't know what to do.
