For me I can punch but it is like getting hit with a wet noodle. I can also run and fly if I find out I am in a dream, usually by talking to another person because I feel like I am talking to myself.

I dont even remember my dreams and the few times I do it feels like a deja vu afterwards. I guess this either means that I have no imagination or that my memory is so shitty that I forget my dreams instantly, Im not quite sure which is more probable.
