I’ve only experienced this around 3 times before. I’ve found that very very rarely, when I’m lucid, I experience an extreme emotional shift where all of a sudden, I will feel extremely happy.

This has always happened for me when I’m lucid and I decide to stop following the plot of the dream and just do whatever I want.

An example of this was recently when I became lucid and stopped following the story that was happening and I entered a sort of resort with a glass roof and just stopped for the rest of the dream to look up into the sky. Another time when this happened, I stopped while climbing a tower and looked off into the distance and just observed my surroundings and thought “I don’t see a view like this every day”

For me, this feeling comes when I both become lucid and instead of trying to use my powers, I decide to sit and relax. Not sure if anyone else has this experience but interested to see.
