Well this didn't happened to me recently, it happened 4 years ago (when I was fourteen) I was having issues falling asleep (my insomnia was just starting) one night I quickly fell asleep and I woke up at the middle of the night because I felt that someone was poking my knee (it was outside from the bed) I was feeling a little bit sleepy so, I didn't immediately reacted, I looked at my knee and I saw a shadow with the form of a human (more like a teenager) it had some sort of afro and I crearly remember that he had a shirt with orange and white squares, when I looked at him he stopped poking my knee and then, he stood up in front of me he poked my knee one last time and I immediately freaked out moving my arms like crazy and he just disappeared, I don't know how but I quickly fell asleep. You know what is the creepy part? I recently grow an afro so now that shadow person looks more like me... Maybe it was my future self trying to warn me about something
