Is it normal that sometimes when i close my eyes...?

So sometimes when i close my eyes, and say i,m think about roof top, the picture start spinning till it fades away. And say if i think about my bedroom..so i close my and start thinking about it the pic in my head is upside down and no matter how hard i try to think of it in a real way it wont move the right way. i have to open my eyes and then shut to see it in its right place. (And of course i can think about stuff without closing my eyes - just saying it happens when i close my eyes). So dose anyone else have problem like this? not that it is a big problem to me...just wondering if it is normal? stated happening about 2-3 ago...dont know why, havent done anything different since i dont know when.
