Read more books. Watch fantasy shows. Something that spurs both motivation and imagination (it has to be fun). I wrote down everything I wanted to achieve in dreams like dream skills and characteristics items. This helped a little bit. Especially because i pictured it vividly in the back of my head and this is now a memory which i can more easily access.

Do meditation. Deep breathes. Long inhales. Keep oxygenated. Try that in a lucid dream as well when you are having headaches.

Just my 2 cents. Not sure if good advise but maybe it helps Hope you don't lose all interest in LDing. It is a great thing. Good luck brotha!
