As someone that has lucid dreams nearly every night, it's just so tiring. You never get any rest. I wish I could make it stop.
There are some benefits to it if you're able to harness it. I've solved plenty of different programming problems in my dreams, only to get up in the morning and then go through the motions again to make them real. Sometimes it feels like the day is just on cruise control because you've already done this.
So for you do you spend whole 8 hours lucid and does it actually feel like that?
If I had to pick one or the other, I would say that it feels slower... maybe more like tedious since I can't actually accomplish much.
Alternatively, close your (dream) eyes and let the dream dissolve intro dreamless sleep. You will still be lucid, but there will be no dream, only empty consciousness. It feels sort of like floating disembodied in an empty boundless dark space. It is a blissful experience.
If you get bored of that you may be able to recreate the dreamscape, just like when you perform WILD.
I doubt it’s a “trip” they’re after.
I’ve thought about their dreaming, and my hypothesis is tv noise tricks the brain to not identity or disassociate from the dream. I guess they sleep better than when they sleep in silence.
