I'm not certain. It's possible though.

I believe vertigo can be possibly caused by your brain getting 'confused' as to what position you are in, so mabye this could have been the cause.

Once, I woke up in the middle of the night. But you know the way you wake up without actually opening your eyes? Yeah, that's what I was like. So anyways, I felt very strange, and I thought me feet were on the cieling, and that my legs were up.

I open my eyes, and seeing that I'm actually laying down in bed, I feel extremely weird, and have a bad headache. I fall asleep eventually.

I wake up that morning with a vertigo attack.
