I've recently (less than a week) discovered the possibility of lucid dreaming and since then, have found it very hard to sleep. I think this is due to the excitement of just thinking of what I could do within a lucid dream. Is there any way, besides the obvious "Just try and keep a cool head", that I can decrease my excitement when going to bed? I also have very bad dream recall, usually 0-1 a night. How can I improve my dream recall if I don't recall any dreams? I know keeping a dream journal is a good way to improve dream recall (and I have been writing down any dreams I've had), but if I can't put anything in it how will my dream recall improve? I've been doing random reality checks (and a wide variety of other methods to improve my chance of lucidity), so that achieving lucidity will hopefully not be a problem, the problem is just being able to remember the lucid dreams.
On another note, the dreams I have are really weird and random, is this normal? For instance, me and a troll flying on birds in some odd shaped building. Most of the dreams I read that other people have are normal, like them being in a store, or other common location while doing normal things.
Thank you for taking the time to read this, and any help is appreciated.
