Is it normal that i get this weird feeling and can control my pupils?
Okay ever since I was a little kid I could do this thing ( and bear with me I really can't describe it ) I can control the feeling and it kinda makes me shake. I feel it in my chest,mostly. But also in my head. I watched it in the mirror once, and when I do it, it makes my pupils in my eyes get huge! I've been curious about it my whole life, is it normal?
