I saw a Chinese man once inside my house about a decade ago, he was very short and just stood there doing nothing. I did not see him again.
I also saw three women dancing in my living room some years later. All three were extremely short and reminded me of Boticelli's Primavera. I walked up to the apparritions and walked around it, which then slowly dissolved.
I saw my long deceased grandmother, she was standing in a crowd smiling at me. She disappeared in a blink. She was her normal size.

When I see stuff that isn't there LOL, the scale tends to have no relation to physical reality, and my mind has no issue with it.
