Two night's ago I asked my mother and stepfather the same question as we were dining at an Italian restaraunt (no alcohol). My mother also made a nonchalant remark about how natural she could control her dreams and that she could always tell that she was lucid (she used the word only after I explained it to her) when she was having a nightmare or something terribly wrong was happening.

My stepfather just sort of stayed out of the conversation...whether it was out of shyness or that he thought we were both a little cuckoo, I don't know.
