How can I learn to interpret my dreams?
The dream interpretation section on this site covers most of the dreaming process and includes dream analysis, description of sleep cycles, explanation of symbols often met in dreams and methods of remembering your dreams. However be aware that dream symbols don't mean the same for everyone as dreams are very personal.

What is the duration of a dream?
Dreams can vary in length depending on how long you sleep. We usually have our first dream after about one hour of sleep and it lasts about 15 minutes. REM sleep occurs every 90 - 100 minutes, 3 to 4 times a night, and lasts longer as the night progresses. The final REM period may last as long as 45 minutes. Less vivid dreams occur at other times during the night.

Can I choose what to dream of?
Some control is possible however it is quite difficult to determine what you will be dreaming. A helpful method is to set your mind on what you want to dream about right before you go to sleep, by giving yourself per-sleep suggestions. If your dream isn't what you wanted insist on it until your dream satisfies you!

Do people know when they are dreaming?
Sometimes yes. You can teach yourself to recognize whether you're dreaming or not and grow your skill so you can choose whether to interfere with the dreams’ natural flow. This is known as lucid dreaming. Studies have shown that if you wake up an hour earlier than usual, then go back to sleep, that you’re very likely to have a lucid dream in that last hour of sleep. Some studies have shown that lucid dreams are more likely to occur in the sixth hour of sleep.

Are the people we see in our dreams real?
Sometimes they are but other times they can represent an aspect of us. See it as the universe mirroring back to you that which you need to recognize, appreciate or resolve within yourself.
