It’s been going on for a few years, whenever I get into bed I hear a child’s voice in my head saying “Wake up” over and over for a few seconds. For the first few days I thought that I had read too many creepy novels and things like that but it kept going on. Even when I’m tired and I am not even thinking of anything, right when I get into bed I hear “wake up”. It’s happened almost every single day. It’s weird but I’ve sort of gotten used to it.
