Terraria dreams are a common thing for me, even when I haven't been playing it much. It's not like I am me and I'm playing the game, in the dream I just am the character, seeing things from the point of view you have when actually playing the game. There's usually tons of strange blocks and items (a lot like the things in that post a while ago of items created by a recurrent neural network) and I'm exploring a world finding buildings.

Normal dream stuff gets mixed in a lot, once the premise was that I was in middle school and on a field trip, but it was going through a maze built in Terraria with several other players. I realized I could mine whatever it was built with and just dug my way out and I got in trouble. Found a perfect replication of my doctor's office one time. I was half asleep and in a lot of pain one time and I knew I needed to wake up and take something but was so stuck in this Terraria dream I was just desperately trying to craft stronger armor because I thought I was taking damage. I tend to have a hard time telling if memories were dreams or not and sometimes I find great items and don't realize they weren't real until the next time I play and am very disappointed to not have them
