<human>: I was talking with my friends about sleeping and how we dream every night, even when we don't remember our dreams, unless time passes instantly when we sleep. They said that I was wrong, and I asked them if time just passes instantly when the sleep and they said it does. This blew my mind because only once in my life have I ever perceived no time when I sleep. Every night, besides that one time, it feels like many hours have passed when I sleep, even when I am not consciously dreaming. We were thinking that this could mean that I am never fully asleep and not getting complete rest, but I am not completely sure. So, do other people experience this, or do I just have a fucked up way of sleeping?

Could you distill the essence of the text into 1-3 sentences?
<bot>: My friends say that they don't perceive time when they sleep, and I have only once had a full night's sleep that seemed instant. Is anyone else like me, or am I just a freak?
