Dreams swim

I dreamt that I was swimming in lovely deep clear water and a voice telling me to mikveh. what could this mean?

Swimming in ocean with old shark

Was in the water naked and battling to swim

Michael Jackson was floating in a swimming pool full of propofol and little boys

I remember a little bit of a nightmare the reoccurred only twice (I’ve only ever had it twice, wasn’t sure how reoccured would be used here). The only little bits I remember are that I was with all my cousins on my mom’s side and that it took place in a haunted house. I remember walking across this hallway but the view had zoomed out and I could see through the wall. While the view was zoomed out I could see two massive dog heads barking (like a cerberus type thing) over top of the house. Then we climbed up a rope ladder (like the ones in the FMS swimming pool) and arrived in a massive room. In the far corner of the room was a pyramid type thing made of wood. The pyramid was much closer to a Aztec on then a Egyptian one in design. Then I remember turning around hearing a scream and something coming out of the trap door. It had a similar color to the creatures from the moon in Destiny 2 (oddly I’d not played the game at this point yet, barely knew it existed)
