Sleep time: do you prefer it to be completely silent or some background noise (fan, music, tv etc)?
I wear earplugs to keep it quiet. (Read: to keep Mr PAK's snoring from annoying me!)
I am a day sleeper half of the week. I LOVE working the night shift. And I always sleep with the TV on.
I have to have a fan or an air-conditioner going to sleep. I cannot stand the silence.
I love a fan but the best is always when it rains! Puts me right out.
I purposefully get the loudest fan I can. I live by the highway. It's perfect.
I go to sleep listening to an audiobook. That takes 5 minutes. After that, I don't need or want any background noise. So I voted silence.
