I always slept with the light on when i was younger only when a boyfriend moved in with me who was used to sleeping in the dark could i cope with it being off.Now i hate having a light on!


Answers:

I presume in this situation when you put the light on it gives your brain something to concentrate on other than the pitch black and your thoughts, which then allows you to drift back off!
