Not so much scary but kind of crazy, and something I cannot explain or understand:
In high school I had a friend, we'll call him, John for these purposes. Me and John played football together and we would always get extra lifting sessions in at the high school gym. We remained friends after high school and even worked together for a bit. He ended up getting into selling pills and our relationship deteriorated to the point we were no longer speaking.
Fast forward a few years later and I have this dream. In my dream, I am back at my high school gym lifting weights with John. We were just chatting about random stuff, having a good time and then he suddenly says that he has to go. I tell him I don't want him to leave because I want to keep hanging out and I missed him. He just says he's really sorry but has to leave, I say "OK, see ya later" and he replies with a nod and a "See ya".
I woke up to the sound of my phone ringing, I see it is my mom and answer it. She tells me that John had died last night and asking if I am OK and other mom stuff. She had heard from Johns mom who called in saying that Johns siblings would not be at school the rest of the week because of his death. My Mom was a secretary at the school they went to.
I can't help but think that something paranormal had happened to allow me to make peace with and say goodbye to my friend and have some bit of closure. He was 25 when he died of a overdose and was the first person really close to me who had died.
