I’d create my own mansion where I would always start my lucid dreams and every room could have a different purpose. I could change it all and make it really cool looking and design it all. It’d rock.
Or do something fun that you did recently that you can’t do anymore:
Recently we did ping pong in gym and now we aren’t doing it anymore. I could play ping pong, and it’d rock!
Or dig a hole to china!
Or turn into a monster and scare people on Halloween.
Or practise something in a dream. Like pen spinning, magic tricks or some other thing that takes practise. oh oho ho I want a lucid dream!!!
