Sox- no idea on that one. I have had it happen if I am reading, but it is because my ON sneaks in when I am reading, which makes me feel like the room is spinning and makes me want to hurl.

Mom has been having dizzy spells like that lately, it started after they changer her prescription on her bifocals. I think that is what's causing hers. She is going to the doc to check it out just in case.
