This is really hard to describe but it is very unpleasant.
Basically it seems like all the action around me speeds up including others' speaking to such an extent that i end up moving and talking very slowly. Peoples' tones also seem to change in my head.
This is accompanied by a very strange feeling in my hands and everything I touch feels small.

There are other symptoms but i really cant explain them.The whole thing can last from 3 to 5 minutes more or less.

This hadn't happened for a while but two days ago it came on at its strongest, everything was faster than it had ever been and i really started to panic. It also lasted for a good five minutes.

I have been to doctors and i was tested in hospital to find out what it was, but since they could not induce it they could not work out anything about it.

I would like to know if anyone has heard of anything like this? and if it is potentially dangerous?

Thank you
