Since I was 10 I do lucid dreams. There are days that I struggle half a day to be 100% sure I'm awake and the other half to assimilate it.
For me this is really exhausting for three reasons:
1. the brain needs to properly sleep
2. they are so rich of details
3. they condense in 7/8 hours maybe 5/10 years of life
Basically they are what I think is a kind of parallel universe. I'm used to tell the entire "dream" to my GF. She always been astonished by them. They seems absolutely unrelated to anything I saw hear etc... during the day, they are in some case "boring" in the sense that I'm dreaming me in a totally different life, job etc... nothing "exciting" or "strange".
Your brain can only generate so much pseudorandom visual imagery per second; an effect that you can exploit to control how much and whether you're lucid dreaming. For example, if you fly up while looking down eventually you'll overwhelm your ability to generate a detailed geography and wake up. Or at least, that's how I manipulate my LD state.
