I also have a question
Why is it that you can sleep all night in the same position and wake feeling all refreshed and rejuvenated with no ill effects whatsoever, but when you sit or lie in the same position for too long while awake you get uncomfortable and then lingering aches and pains?*

*may have spent too long lazing on arse recently

Btw, this is a serious question. I have been sitting here for some time (getting uncomfortable) pondering the biological/physical mechanisms behind it.

Actually
when I lie on one side all night my ear aches - the one I've been lying on, obviously.

I also believe we move all night even if we don't know about it - that's why my chocolate stash keeps disappearing because I'm eating it during the night, apparently.

I have to sleep
On my left side.
Or I get really bad acid reflux.

Strange but true.

I only ever lie in one position...
After getting absolutely spannered and I wake up in agony with the ear thing and a really sore collarbone.

@ Al
How many times have I told you not to lurk under there! And I take it you're responsible for all my underwear going missing? Six weeks I've been knickerless!

Yeah actually
I too have woken to a throbbing ear.
And dead arms too. I always think it's funny when you wake up and have to pick up your lifeless arm with your other one, waving it about like a proper 'tard.
Once though, I managed to cut off the blood supply to both my arms. It's surprisingly difficult to move at all when you have awaken woolly-headed with two dead appendages. Ever done that thing where you flail your body about to make your arms dance of their own accord? That's what I was reduced to.

I once
fell asleep sat down, with my elbows resting on my knees and my hands supporting my head. When I woke shortly after and stood up, I just fell over. Tried it again and fell over again. My still-fuzzy head couldn't comprehend that my legs had gone numb...

But in answer to your question, I'd guess that we move around loads in our sleep to prevent this, maybe our subconsciousness makes us move when it feels pain we can't recognise because we're asleep. (Purely a guess and has no scientific theory in it!)

Haha!
Thanks gin, that made me laugh (and feel like less of a spakker).

I spose that must be it... although I've been told a few times when sharing sleeping space that I haven't moved all night. Hmm. Praps I shall set up a camera and conduct a sleep experiment. *considers logistics* Praps I shan't.

Also, went to sleep once whilst with ex, with a full unopened packet of McVities finest chocolate biscuits next to the bed. Woke up and found the packet empty save for one solitary biccy in the bottom. I waited for him to wake up and waved the packet accusingly at him.
"Ah shit" he mumbled as he came to, "I thought I was dreaming so it was ok to eat them all".
"But you left ONE!" I said, perplexed.
"Oh yeah" he replied "I thought I'd better save you one..."
The image of him gleefully nomming for England under the impression that they were dream-biscuits still makes me laugh, not to mention his surreal thoughtfulness.

Once he dreamt he was eating toothpaste and woke up with a strange intense burning sensation in his mouth... a short investigation revealed a nearby tube of Deep Heat missing its lid and woefully depleted.

Truly teh sleep makes us all fuzzy, spakkering simpletons.
