When I was at college, and in my early 20s, I only needed 10 hours sleep per week. (I only went to bed, for a few hours, every second or third night).
Nowadays I can sleep for 10 hours at a time but that doesn't make it any easier to actually get to sleep. (I'm usually in bed for at least two hours before I start to drift off, but it can be much, much longer than that).
I go to sleep very quickly and then wake up after a couple of hours, spend the night mostly awake or dreaming vividly and then am shattered every morning. Actually, I can sleep better during daytime hours than I can at night.
can't sleep purely because of my bf's fan blowing across to my bed and his snoring, we have separate beds so I can try and distance myself from the noise, but it's still bad, I would move my bed into another room but I don't want to move our closeness as a couple even further apart. In the past I have also been unable to sleep because my mind just doesn't shut off.
