Lucid dream is a dream during which the dreamer is aware that they are dreaming. During a lucid dream, the dreamer may gain some amount of control over the dream characters, narrative, and environment; however, this is not actually necessary for a dream to be described as lucid. source by Wikipedia
Is lucid dreaming scientifically proven?
Yes. There are many examples of scientific research that prove the existence of lucid dreaming.
In fact, lucid dreams provide credible explanations for night-time phenomena which until recently had no scientific explanation – such as alien abductions, astral projection and out of body experiences.
The first scientific proof of lucid dreaming emerged in 1975 from the British parapsychologist Dr Keith Hearne.
He recorded a set of pre-determined eye movements from his lucid volunteer, Alan Worsley, via an electro-oculogram (EOG).
What can I do in a lucid dream?
A fully lucid dream can be perfectly tangible, rich and visually detailed.
When probed, it can generate seemingly impossible levels of self awareness – such as 360-degree vision, multiple simultaneous dreams, and even visual representations of the fifth dimension.
Because all of this takes place in your mind, the dream world is infinite.
No laws. No boundaries. No limitations. Anything you can conceive of comes true.
You can literally take control of your dream and warp The Matrix like Neo. Fly and soar over cities like Iron Man. Slow down time like the dream levels of Inception. Have sex with celebrities. Fight like a ninja. Re-live childhood memories. Base jump. Survive death. source by world-of-lucid-dreaming
