My 2 yo sees things that aren’t there

I was putting my daughter to sleep today, and she was looking to the wall that’s next to her crib. I said what are you looking at? She says, there’s a man. She’s 2 years old. She says he has blue hair, and black eyes. He Came to love her. (Iove her in a childish way).

Then I asked to point him out, and she pointed to the wall. I asked her to tell him to leave. She asked him and she said he moved to the other corner.

Guys. I’m freaking the fuck out. Is this common? Should I be worried....???
