That's mixed bag of responses. Last night I was very tired after our drive home from our daughter's home. When we arrive home after any time away, I unpack right away. Last night I simply could not locate a favorite hat that I had taken with me. I woke up a couple times with that on my mind. I finally got up and went to look in our car. Sure enough there it was, hiding between the seat and console.
On top of that, because of my sleep apnea I have an inspire implanted neurostimulator that you turn on when retiring at night and turn off in the morning. I didn't want to wake my wife and couldn't find the remote control in the dark. So during my excursion to the car seeking my hat and back the inspire was doing its job. After finding a flashlight I located the remote and turned off the inspire device. My wife found me in a recliner in the den and wondered why I was asleep there. Sometime the best answer is simply to say, I couldn't sleep.
