Spinning during HI

Has anyone tried this?
I seem to get a lot of that Hypnogogic imagery stuff in the morning and this morning I tried something new.
I was wandering around the back yard of a house. Lawn, concrete path, white picket fance completely normal but nowhere I recognise.
I thought I'd give spinning a go seeing as I had such an odd and unexpected LD fro a previous HI.
At first I just got lightly 'bumped' awake and realised that my body was actually trying to do the spinning :?
Second time it was a little diferent. There was a realy lound strange ringing in my ears and I was JOLTED awake very suddenly.
Anyone tried using this as an entry technique? It' seemd to to the complete opposite of what I expected :(
