I never really understood, and any definition I read, I just forget after a while. can someone explain in a way that I won't forget.

the water analogy doesn't help as I get confused between them. also, Watt is the most confusing for me shouldn't it with some unit of time ? like I could say how much water is flowing per second but just saying how much water is flowing without the time wouldn't be very useful, it could be seconds, minutes, hours. yet, the Watt is never written with respect to time, why is that?

I don't mean this in the sense of "if I have a sex dream that involves my mother, does that mean I am attracted to my mother?", I know that dreams aren't a literal representation of our desires in that sense.

What I mean more is, is there any study or anything that has been done to see if a dream's content indicates anything about what problem the brain is trying to work out?

Like does a dream about sex indicate that a certain lobe in the brain is particularly active at that moment?

Or like I have had negative dreams that cause me to feel anxiety when I wake up that involve my family or where I was in the middle of an ICE raid recently, does that indicate anything in particular about what my brain was doing while I was asleep that caused me to feel anxiety and that happened to manifest as ICE raids?

not sure if this was the right sub for this question.
