perhaps it was a vampire...

so, i would appear to have no blood anymore.

seriously, it's 21 degrees in the house and i'm freezing. normally we keep it at 19 and i'm fine.

not only is it 21 degrees and i'm freezing, but i've got socks, slippers, pants a shirt, a sweater, a vest and another sweater AND a hat on. and i'm still freezing.

i'm not hungry. i'm not tired. (the two things that tend to make me cold) i'm just inexplicably freezing.

so, my new theory is that i was visited by a vampire who sucked out a bunch of my blood, but just enough for a snack, not enough for a meal, and so i didn't notice, except for my sudden inability to get warm.

seems plausable to me...
