I'm a natural LDer, and I can pretty much sleep as little or as much as I want (I'm a housewife with no kids), so I have a distinct advantage over most people.

I have been keeping a DJ for ONLY 20 days and I feel like they have been pretty normal for me, dream and sleep wise. But I might be wrong, as I said, I've only been keeping track for 20 days. In that time I've had 82 lucid dreams that I remembered. Divide 82 LDs by 20 days for an average of 4.1 LDs a night. That includes a few nights when I didn't have any LDs. I'm interested to see how the average changes or stays the same over the long run. Hopefully in a few years it will be a lot clearer.

What is normal for me isn't necessarily going to be normal for anyone else. But, yeah, it is possible to have a bunch of LDs.
