I can’t have have dreams unless I get eight or more hours of sleep but I can dream in naps it’s weird
I don't usually dream much, but I usually have to have a clear mind, a cold room and i only require like 5 hours of sleep to dream
I sleep best in my bed.
Not in a concrete parking garage…
If I'm camping in a tent, I hardly ever have dreams
my dreams depend on time- if i fall asleep at a reasonable hour, i usually never have any dreams, and if i do, they're always very hazy. if i fall asleep at, like, 3:00 AM, i'm guaranteed to dream about something strange, and it always immediately leaves my head as soon as i wake up. there's a sweet spot where, at a certain hour, the locations of my dreams begin to recur, forming a sort of dream-world. these dreams are usually incredibly vivid. the human mind is fascinating!
I have noticed that the best way to have a dream (or even lucid dreams or OBEs) is to go to sleep and set an alarm after about ~3-4 hours. I think the reason why this works is that it's harder to remember your dreams if you are too tired but you still need to be somewhat tired. I have also heard that meditating regularly can increase the amount of dreams you remember.
