Dream #9 - Underwater

In this dream, I was at school reading a weird book with nothing written on it and made of plaster. The pages were also plaster cubes. I then noticed that some of my classmates were missing today and replaced with ones I didn't recognize but I didn't care anyway.

Next I was inside of an underwater cavern (I think I was watching a video of it but idk). On one of the walls was a rocky box with a hole, inside I saw a pink/blue jellyfish. As I swam away from the hole, the jellyfish moved too close to it but never exited.

Finally, I was playing a Roblox tycoon game where my old avatar was stranded on a lifebuoy (or inflateable ring) and I had to eat fish to survive. I dove underwater and saw lots of them.

Guess I was excited to go to the beach today which I did. I went to an old beach I visited years ago and think I was misremembering at the time. I thought I saw a very long tunnel underwater leading to the other side. I tried finding it again but couldn't because it's gone now. However, I did saw lots of fish and a stingray too (forgot I saw another too on my boat trip which makes the count up to 2 this year). I even found small treasure underwater (just a Cent)! ^^
