Do me a favor! Sleep and Dreams.

It depends on a lot of circumstances really. The temperature in the room, what you have eaten or drank before sleep, the comfort of the surface you are sleeping on...there are many variables. If you go to sleep in a warm room, in a comfortable bed, haven't eaten anything for a few hours and aren't disturbed, then chances are you will have a few dreams. With lucid dreaming however, it works almost the opposite. You are going to want sleep disturbances roughly every hour to prevent deep sleep or REM sleep. This will prevent regular dream routines and give you more wild, unpredictable dreams that you can find yourself in control of.

There is nothing mysterious or threatening about sleep and dreams because both attributes are hard-wired into the human brain and body by billions of years of evolution. Sleep is nothing but a survival mechanism to prevent us from falling off cliffs and from being devoured during diurnal periods of darkness. Sleep also serves to rejuvenate and restore many of our physiological and brain functions and allows us to face every new day with optimized mental and physical resources. Dreams are essentially the random firings of part of our brain and are necessary to keep us in a state of semi-alertness while we are sleeping. Dreams may also serve to reactivate and refresh our physiological systems. Unless dreams become very repetitive or frightening, such as very frequent nightmares dealing with similar subjects, it is fruitless and confusing to attempt any interpretations of our dreams. The random firings of our neurons do not follow normal neurological pathways.
