Mine use to be like that all time, I think it mainly had to do with the fact that I was so interested in LDing at the time that I spent a lot of time researching and practising. Apple juice always seemed to help as well. Just keep practicing different technique and remember to think outside the box. If you manage to find a remote in your dreams, look for a "vividness" button and turn it up. It may sound ridiculous but it'll work as long as you believe it will. Vocal commands are effective as well; a simple "increase clarity/vividness" will go a long way as long as you're sure of yourself.
