Dream-quest by UnknownKadath

This dream was in the middle of the night and I should have gotten up and written everything I remembered in my journal. But I would have had to turn on the light to see what I was writing and I just went back to sleep. I should do better.

But I remember this: I was competing in some kind of obstacle course and there was a puzzle aspect like identifying objects along the way that had a theme to them. My course had a semi-deep rectangular hole to run through, a seat to jump over, and a tool to grab and carry with me. I figured out that three were the theme in that they rhymed. Trench, Bench, Wrench. I felt so smug in that no one else would figure it out, mostly because 'trench' was a little-used word and no one else would think to call the hole a trench, they'd just say hole or something similar.

I own a pair of wireless earbuds; they're black. In the dream snippet I was in my room with two of the black pairs plus a pair in white. My earbuds have L and R on them despite being the same shape and looking neutral. But in the dream I was thinking that if I couldn't match the correct case they'd either not charge or even break. Not an issue for the white pair in a white case, but the black ones? And it didn't help that I had one extra black earbud marked not L or R, but 73A. So five black earbuds. Well as long as I was confused I decided to try and charge both L's and listen with them and do the same with both R's, just to see if they'd sync to each other. I guess I was willing to risk breaking them all? And then figure out what the 73A one did. There was someone I didn't know with me who was going to help me with this, but I woke up.
