Hi folks!

I've noticed a change in my lucid dreaming patterns and would like to get your input on it. It seems that my lucid dreaming has changed to cluster mode, which in itself is not too bad since at least I'm still having them. Here is how it goes.

I'll have a one to two week dry spell and then BAM! I'll have two to three nights with 3+ lucid dreams each night.

What I would really like to figure out is just WTF is causing this? It would be nice to know both what is causing the dry spell and what causes one of the clusters.
