First Lucid Dream- Why Did It Happen?

I have had lucid dreams before, but none really counted. The only one when I was fully lucid ended after a few seconds. The rest I was just partially lucid.

Last night, I had my first lucid dream. I was not entirely lucid, but I knew I was in a dream and remembered most of reality. I would discard this as mere chance, but in all my dreams that night I was semi-lucid. The difference between last night and any other night was that I was sick, and I went to bed much earlier than I usually do. In fact, I may have not gone to bed that early in months, or even a year. Could this have caused the lucid dream?

I think so.

For me I lucid dream more when I either,

A. Sleep during the day or,
B. Sleep, wake -up , and then fall back asleep.

I have two theories for why this happens. Both are essentially the same thing.

Time of Day. When your body is conditioned to be awake during a certain time, and you end up sleeping during that time. So you are essential awake in your sleep. This would be dependant on your routines.

An Awakened State for the Waking Life. When the body's condition wants to be awake but you are choosing to sleep instead. Making it easier for the body to attain a waking state while sleeping. This would be dependant on your intentions for that day.

This is what I have found during my lucidity. Does this help?
