It is certainly possible to dream about dreaming. But the ability to control dreams and intentionally (consciously) move from one dream into another then another, or to move in and out of other people's dreams as portrayed in the film Inception, is pure Science Fiction fantasy. See attached link for further comments.
Lucid Dreaming
It is not possible to "wake up" in a dream. When one awakens from a dream, one is no longer asleep, and no longer dreaming. Some individuals are able to become aware that one is dreaming while still in the process of dreaming, which is called "lucid dreaming."
No, lucid dreaming occurs while one is still fully asleep, but becomes aware that one is dreaming as the dream is taking place. Once one awakens, the dream, lucid or otherwise, has ended.
Most people dream every night, but not everyone remembers that they had been dreaming.
In a lucid drream you are aware you are dreaming and can take the dream where you want to go, or to someone you wish to see. When u day dream u are not actually aware of your dream state.
The scientific term for the ability to be aware that you are dreaming while still in a dream is called "lucid dreaming." It involves a state of consciousness where individuals have awareness and control over their dreams.
"Somnio securitatem" is Latin for "dream security" or "security in dreaming." It could refer to a sense of safety, protection, or peacefulness experienced during dreaming or while asleep.
Dreaming is uncontrolled thought during sleep. To dream up is to develop an idea, plan or thought while awake.
Dreaming ʕ ꈍᴥꈍʔ
Nope. A dream is just a dream.
If you would like to lucid dream, you should start trying to remember your "normal" dream after you wake up. The purpose of this is: If you can't remember regular dreams, there isn't any way you'll be able to remember if you had a lucid dream. All lucid dreaming really is is being conscious of your surroundings while in a dream. If you can realize that you are in a dream while in your dream, you will become lucid. There are hundreds of different ways to learn to lucid dream. The most commonly used one is asking yourself throughout the day if you are in a dream. Chances are, if you do this in your dream out of habit, you will realize that you ARE dreaming, and become lucid.
The correct spelling is "dreaming" (subconscious mental images and activities).
