Sometimes when I'm sat either watching TV or at the computer - or thinking about it doing nothing at all I get a very odd sensation - it's like I've drifted off somewhere else for a minute and then I get a jolt go through me like bringing me back to myself.

I've had this on and off for years - but it happened this morning just sat at the computer - thinking about nothing in particular and yesterday when I was in the dentist waiting room and as soon as the door opened and the nurse came out it happened.

I've often wondered if it is that I've relaxed temporarily (relaxing is NOT my thing!!) and the jolt is my brain saying I have to always be in alert mode?

The jolt yesterday and today was very obvious to my husband who was sat with me as I phyiscally moved and went to hold onto something. They leave me feeling a bit odd for a while too.

I know that today I'm very tired and anxious after the dentist yesterday.

Anyway - sorry if this is a bit rambly - just wondered if anyone else had this sort of thing?
