Lucid dreaming is being aware that you are dreaming while dreaming. It allows people to control their dreams and do anything they want, like flying or talking to deceased loved ones. To lucid dream, people can do reality checks during the day like looking at signs to see if letters change, and asking themselves if they are dreaming. Believing you can control your dreams is key, as doubt can cause dreams to become unstable and cause waking up. Lucid dreaming is used for entertainment but also helps those with disabilities regain abilities in dreams and improves memory.
