I was pretty sure monsters were real because once I slipped from a nightmare where monsters were taunting me and I was just wrapped up in the blanket and eventually I made a run for it and got my mum and was confused that they were gone when I came back with her.
Another time I was looking at a night light falling asleep and a face came up and talked to me, it reinforced my belief. So far I haven't been proved incorrect though =p.
