Paranormal stuff

Why the people who saw paranormal stuff never had good vision eyes or camera? 

I literally just saw small creature near my wall and heard how he crawled there. He was kinda black but that was real. And when I thought that I should write about in in my blog I saw an exact creature bumping into my window OR going through a hole in my wall. But I saw him and heard him. But he/she/it was too fast I couldn't even record them. I should actually just put a 24/7 security camera in my room. 

P.S. I have - 8 vision and never diagnosed with schizophrenia. 

I should actually posted this in 4chan, not here...
