It could be a reaction but you might still want to check it out. I know I can get dizzy if I think too hard on something. I hope you feel better and stay feeling better. As for the forgeting what was said in session, I can relate. My T asked me a question. Then, she asked me why I was acting weird. I said "I don't know." But, I lacked any conscious thoughts at that moment and lost the question that she had ask. Lucky for me, I have only done that once and suspect that the question worked itself out in some odd way. (I think I know what the question had to do with).
