To put it simply, you were worn out from work.

An hour has passed since midnight, and you haven't been able to sleep for the last few seconds. You push your cover away for a more cozy chill and branch out your limbs with an ache, just to melt onto your back on the bed as you attempt to close your eyes and get some rest.

It was almost like you were asleep. Up until your body jolts and you start to gag with a tentacle over your tongue and slithering across your body.
