A fine hello!

I can't say anything on the subject on astral projection. I haven't experienced it.

On the subject of LDing, it's great that you're keeping a dream journal. Nightmares are actually the best outlet for learning to LD, and they provide very obvious dream signs. They can very easily lead you into a DILD(Dream Induced Lucid Dream).

I suggest you sign up for the DILD class in the DV Academy forum. Other experienced LDers will help you along the way, giving pointers and assistance.

Hope you have a LD soon!
