Current dream you thinks younger you thinks current you is getting pervy and showing it to you dramatically to get your attention. Might mean you’re crossing through a doorway and current dream you believes younger you is going, “hey Koen! Don’t forget about me!”
could be why it popped up in your dreams instead. You weren’t thinking about it actively but something was churning in the background.
Then again, I have this take on dreams in general:
If you go back over the things you saw and talked about during the last waking period, you might be able to find what things the dreams metaphorically represent from those topics.
Might have had nothing to do with porn or yourself when you were younger. But they might symbolize something you talked about or saw.
