Lets say what it really is.. "timetravel" 

Lucid dreams are timetravel  

 I'd count it in my book! I think anytime you're more than a passive observer experiencing a movie and have some agency in what you're experiencing, it counts. Even if it's just directing the camera. You're consciously affecting your dream by reaching out into the dream world and imposing your will.

I used to be able to do it often when I was younger but I rarely do now. Too tired most days I think. 

 Same. I kept a dream journal and everything when I was younger to try and improve dream recall.  

 Oh man I wish I did that. Would be so interesting to go back and read it 

 time to start ;) 

 I wish I still had it.
