Follow up on what happens. Perhaps it will help.

I can say I was experiencing my longest dry spell of lucid dreams this past winter. I also was the least active I have ever been. I normally would play basketball twice a week in the winter. Due to an injury I did very little.
NOW. I am back to landscaping and very active. I have had two nights of consecutive lucid dreams and three more in this short duration.
The changes
Activity
The time change. more light of day and also the time change of the clock
The changing of the season. (another experiment)
All of which could play a role.

A more effective way is to take out as many other variables or changes. Then take an inactive person and change their activity routine alone.
