I hate it when my sleep pattern becomes erratic. Something happens to throw me off . . . I get too much, I wake up from dreams, something . . . then it becomes a pattern and I wake up in the middle of the night and have to preoccupy myself for an hour or two before I'm restive again.
And of course there's always the paranoia that if it becomes too habitual that I'll throw myself off.
And I have to be up for work in an hour and a half. ::sniffle::
