We know a ton about dreams, we just don’t know why exactly sleep “recharges” the brain which I find fascinating.
This guy assumes people write off dreaming but when I was 17 I was utterly fascinated with the subject and researched lucid dreaming for many years, even teaching myself how to do it. That rabbit hole is absolutely wild.
If anyone is interested in the subject, check out the book “Exploring the World of Lucid Dreaming” by Stephen LaBerge, or watch the film Waking Life.
Yeah sadly weed is really bad for your sleep, akin to alcohol.
When I stop smoking for a few weeks, my dreams become dramatically more vivid and my sleep quality is much better.
