How do I stop seeing things at night?

Just a month ago I began watching creepy YouTube videos for fun, and like conspiracy videos and such just for fun.

However, ever since I’ve been having corner visions and seeing things move. And one time I literally saw a really small black figure kind of hazy or Smokey staring at me , the eyes were like a snail, but as soon as I notice it, it ran off. Another time I kinda saw a tall black shadowy figure run float really fast through my room. All of this happens more now that I’ve started sun-gazing and meditation.
PLEASE SOMEONE HELP, I DONT WANT TO SEE NO BS!

I don’t even know which ones are the good ones and which one are the bad ones. But I just don’t want to continue to see things. It’s really affecting my sleep!

OR AM I JUST CRAZY AND SHOULD SEEK PROFESSIONAL MENTAL HELP

Also this is happening in my tiny room alone and not the rest of the house.
I’m 24 by the way, never before Dec 2021 have I ever seen anything and I was glad for it. For those of you that see things , when did it start and why and how do you deal with it.

And my cat also sees things in my room, but he isn’t afraid he just looks.
