Tricky question. Once I finally talk myself into laying down, it takes fifteen minutes or less to fall asleep. Of course, that does not mean I stay asleep.
I usually wake up at least twice because I’m searching for something in a dream and wake up looking for whatever it is. One time I woke up in the parking lot of my apartment building. Luckily I had pants on.
A good night’s sleep is sometimes elusive at my house. I’m open to suggestions.
I found this cool poster of the side effects of sleep deprivation on Pinterest from Anna Anderson Walker. She also has a blog “Torchlight Conceptions” at http://aandersonwalker.wordpress.com/ Her latest blog is about sneezing. Interesting stuff.
