Some time later, either the noise from the wind or the door outside my appt to the stairwell convinced me that someone had walked into our apartment. I tried to shout "Hey" to scare the intruder away while I fought for consciousness. Needless to say, there was no one there.
Then I went back to bed and slept until noon.
Now, I go eat something and see if I start to feel less like I've been beaten about the head with a bat. If not, I'll call the doctor.
