Where do we go when we sleep?

I spend most of my days sleeping. In class, in the car, in the LRT. I can sleep almost at most just by sitting down, actually I can sleep while standing too, in the bus and in the LRT. 

And sometimes, during these times, I am completely zonked out, that sometimes I feel as if I am no longer in the classroom or in the car. 

Sometimes I wonder, where do I "go" during these times?

My professor in RELSTRI said that sometimes when we sleep we experience astral projection, which is when our souls are seperated from our bodies. And our souls get to travel in this space. So do my soul do that? Whenever I dream of someone, does that someone dream of me too. Am I visiting them? Or are they visiting me? If they are visiting me, does that mean they miss me? Or are thinking of me?

If I were to continue wasting my life in sleep, I would really like to know what happens to me during this time. 

I am officially a hypersomniac

It's a Saturday, and I know there are things that I have to do before next week, but…

I went to sleep last night at around 2, which is well, normal for me. Then I woke up at around 12nn for lunch, sothat's 2-3, 3-4, 4-5, 5-6, 6-7, 7-8, 8-9, 9-10, 10-11, 11-12… 10 hours. Then after lunch, which is around 1ish, I slept again on the couch, I was just sitting there and watching TV then got bored so I lied down, and slept until 430ish, so that's more or less another 3 hours. So it's not even night time yet, and I already had more than my fill of sleep.

I am officially a hypersomniac- the envy of all insomniacs.
