Feeling dizzy

I had a bad dream last night so I was awake early.   Naturally rolling left and right trying to gain a bit more sleep before dawn.   When I rolled left the room was spinning around me so I stayed flat.   I wondered if that was VBI again like I experienced January last year.   When I turned flat again the spinning stopped almost momentarily which wasn't quite like last time.

I gave it another try after a while, i.e. roll left, it was like flipping a switch and the room started spinning instantly again.

The heart specialist doctor said this issue belongs to ear specialist.
