This is the best method I’ve come up with to date.
To optimize the frequency of psychologically esoteric dreams—if you’re into that sort of thing—here’s what I recommend. First, you need to wake up an hour early, but still be able to get back to sleep. That means you need to be getting enough exercise in your daily routine, or else you won’t be able to get back to sleep. Then, drink a strong cup of coffee or pop a caffeine pill and go back to sleep. This ought to kick off some pretty bizarre dreams. The caffeine will start to kick in after about half an hour and the last dream will probably take on a mystical sort of feeling.
If you immediately remember the dream when you wake up, write down the details in as literal and autistic a manner as possible. There is probably a method to your dreaming brain’s madness, but it’s almost never immediately obvious. For example, I had a dream this morning where a character was observing some of those atomizers that you sometimes see in the produce aisle, which were watering some plants. He laughed and said “You might as well be drinking cat rubber.” Although this doesn’t make any sense, I had the feeling that he meant the mist coming out of the atomizers was tainted. After reflecting for a while, I remembered that yesterday I learned shipments of assembled parts coming from overseas, and that these were called CAT shipments. I made another leap and realized my brain was warning me about potential contamination in water passing through parts with Chinese gaskets. Like I said, not immediately obvious.
Unfortunately, you don’t get to pick what sorts of weird insights your hindbrain is gonna send you. Chinese gaskets aren’t something I have ever given any thought before.
So there are three skills you need to practice: have the dream (this post), remember meaningful details, and then interpretation. If I figure out how I do the last part, I’ll let you know.
