I feel like I'm about to faint.
This heat is overwhelming, and any attempt at thought just seems to die in birth.
I'm not trying too hard, for fear that the monster may emerge to gnaw my brain for its impudence. "Do not defy me! Obey! I shall sink my teeth into your grey matter and laugh when you writhe!"
There seems to be an oppressive heat on the inside of my skull, festering and boiling until I wish my brain would turn to cold, wet clay. That would be pleasant.
