I am 35. I dream about a huge variety of random stuff, no other recurring features, except I am almost always a child/young person.
Seem to always be in the 8-18 age range. School (both secondary and primary) appears a lot as a default setting even when the actual dream is nothing to do with school. Likewise my childhood home.
This isn’t a recent thing, it has always been the case. It’s normal dreaming for me. Like my unconcious mind hasn’t realised I’ve grown up 
Anyone else?
