All 3 lucid’s I’ve had are short(I wake up) and I am unable to do anything at all(except maybe walk around). Will this diminish with practise, or is there something wrong with me?
gotta learn to crawl before you can fly. it’ll get better, just keep practicing.
My first two ld’s were short, unstable, more like glimpses of lucidity. Then I had a very long, very stable one. Then followed more unstable ones.
But eventually you get the knack of it and get more and more highly lucid and stable ld’s. So keep at it, sounds like you are on the way. 
Thanks guys. Sometimes I think I have more lucid dreams, but I can’t remember them. this morning I wrote down 5-6 different dreams.
