I put that down to the peppermint tea i drink before bed, a regular night time ritual, and the fact that the nights are longer, mornings are darker, so maybe i have a 'second wind' with regard to dreaming.
I don't know.
Although some of my 'summer dreams' have been pretty vivid.
You bring up a good point. Perhaps part of the reason lucid dreams seem to be more common in winter is that the sun rises later and sets earlier. This means that people not tied down to a strict schedule have more dark hours in which to sleep. It's a well known fact that most REM activity happens in the later hours of sleep, which means more and more dreaming as time goes by. Also, in winter we tend to stay indoors more instead of going outside for physical activities. Experiments have shown that we tend to have more REM sleep after a day of mental activity and more delta (non-REM) sleep after a day of physical activity. Both of these factors may contribute to more dreams and consequently more lucid dreams.
