I find that I wake up often during the night when I have had a intensive day. The interesting thing is I'm not dreaming the usual fantastic dreams I notince my mind churning on the problems and information I've been working on during the day. I usually wake up when I have solved the problem and I remember the solution and that's so cool. I don't know what brought that about but it's interesting.
Of course I do find being woken after only two hours of sleep bad because I wind up falling asleep again for the 3 to four hour solid block I seem to need. Snoopy (my pup) doesn't help when I crawl into bed at 5 am I do plan on sleeping till 9am but he's proving to be an excellent alarm clock and wakes me at 7:10 every morning. I have to let him out but am edgy until I can shut him out. He usually wants to play tag. If I try to sleep after he wakes me he gets up to mischief. That stuffs up my sleep cycle. I wind up sleeping till 11am. Although I didn't bother today it costed me later when at 3pm I zoned out till 4. And today I found out that the lino (he rips up) can give him lead poisoning. And I was only worried about the landlord having kittens when he sees what the dog thinks of his dog-eared lino.
Oh I had an interesting premonition dream about the lino too. I'll save that for another time.
