(I think I saw a thread about this before, but I'm not sure...)

Last night I had a non-lucid dream where I was sick and I was experiencing vertigo. It felt really real. I've had vertigo a lot since last year, but it stopped a few months ago. Do you think this was just my mind remembering vertigo or was I really experiencing it while I was sleeping? Because I've been sick for a few days and the first time I got vertigo I had pneumonia. (but the doctor said it was something with my inner ear.)
