Replying to BIG! then small.. BIG! then small...

Dammit! ii alredy posted a thread about how everything u think and speak seepds up, so i'm starting to sound like a psycho haha.

anyways, now i remember this another strange moment from childhood. i'm having one again;
every object you try to focus on, goes small, and BIG, small and BIG. It look zooms into object then it goes back to normal size. right now i'm looking at my pencil and every 0.5 second it looks like as fat as my arm.

and it feels inside your head like; BOOM BOOM BOOM BOOOM BOOM BOOM BOOM BOOM BOOM BOOM BOOM

not bothered to check for spelling mistakes, i don't care.
anyone else had this kind of feeling, And does anyone know why is it happening?
