Interesting. I've always related that type of dream to unsubstantiated worry. I've never thought of it as avoidance, but it's a rare theme for me.  

 I'm curious, how did you find nostr? 

 Came across a paper on decentralized media - thought of it for a while; then chose the client with the best logo  

 Very cool! Thanks for sharing. I've been using it for a while so it's neat to hear how other people discover it.
