Lightheaded/Dizzy During Aneros Use?

I was using the aneros tonight and was listening to the hypnAerosession and I was really in the zone. Was feeling super relaxed etc etc. Then I noticed my head was starting to feel sort of weird. Almost like there was a little ball bouncing around in my head, I wasnt so dizzy that I was feeling sick or anything, it just felt weird, and as the feeling increased, my entire body started feeling weird too...kinda like I was floating or rocking back and forth quickly, I certainly didnt feel stable on my bed thats for sure. It felt awesome. But I dont think it was a super O.

Should I be worried about this dizzyness? I stopped during this phase cause I was a little worried about it.....

Thanks!
