Hi dp, When I first moved to the country, where dark is really dark, nothing but starlight and moonlight, I rigged up a litle kerosene lamp in a bowl of sand and set it in the sink (safety first) before I went to bed.

The cabin I was in was tiny 8x12 (exterior dimensions), with a sleeping loft in the ^ of the roof. I could just sit up when I was exactly in the middle of the ^. Well, as I was 30 big years old then, I decided I was too big for a nightlight and huffed and puffed and made myself go to bed without it.
(Of course, mind you , I had three flashlights up there with me. One on the left, one on the right and one under my pillow.
Just as I went to sleep, I had a terror and popped up into a sitting position on my way to blindly bailing out...... Weelll, KaBoom, the bridge of my nose met the rafter (i was not dead cener), the impact woke me up for a flash, just long enough to realize I had just knocked myself out.

After that, I let myself have a nightlight. No big deal, no big deal at all. I realized I had other things to look at in myself that I could do something about, and turned my attention to them. Ya know? Right here, right now, do what works, ok?
