If it makes you feel better, I used to have similar insights when I took ambien to help me sleep. I would be so confident that the ideas were world changing tech, or fantastic ideas for a book, or whatever. Sometimes I would be smart enough to write them down.

The next morning, they were almost never actually good ideas. I can remember exactly one book idea that is actually vaguely interesting.

When under the effects of certain types of drugs, we’re far more likely to think of ideas as brilliant. It doesn’t mean they actually are, though.
