First off, welcome to DV!

Nothing unusual about your experiences there, lucid dreams are after all "only" dreams. Memories from dreams doesn't work quite like dreams from our waking life. I actually saw an article by a Norwegian scientists who wanted to find out why we usually don't even remember our dreams, which tells me that this is scientifically an unexplored area.

However, if you have had a WILD, you might have experienced remembering more (visual) details from the dream.

I hope this clears up some.
