Sometimes, when it's dark at night, I see people in the dark corner of a room, and they just stare back at me, or wave, then I'll blink and they'll go away, or not be there anymore. Is something wrong with me.
No! This is a perfectly normal thing that many people's brains do! Especially when in the dark, our brains will start to imagine things that aren't really there after a certain period of time looking into the dark.
