What triggers dream lucidity for many people is the realization that they are dreaming. Doing consistent reality checks works for some people. That is, if someone gets into the habit of tapping the top of door frames as they walk through, that can become a reality check. The dream "body" doesn't always work the same as the real life body. In a dream, the door frame or even the hand may seem to be immaterial. Or in stead of touching the door frame, they rise in entirety to eye level with the frame. Or since it is a deliberate activity, the conscious act of touching the door frame brings their conscious mind into the dream.
There are so many aspects of how it works.
I'm a lifetime lucid dreamer. The earliest dream I remember was lucid. My dreams aren't always lucid, and they may have different levels of lucidity. That is, sometimes I can act within the dream, but only to an extent. Sometimes my dreams are full-sensory experiences, and sometimes the reality or lack thereof will jolt me from sleep.
If you want to lucid dream try meditating and try and imagine things. Once you learn how to maintain focus in a relaxed state while imagining things try and increase the time you can do that. Then if you are able to do those things try doing that again only this time fall asleep. If you have gotten used to maintaining focus while being in a relaxed state you should be able to carry that with you when you fall asleep from meditating so it would be just the same as lucid dreaming.
Reality checks . glance at a clock see the time look away for a quick second then look back to see its the same or possibly a minute later . look at signs in the same way. Tap the door frame and feel the instant consistancy. ... These are just examples you can make your own as long as you make a habit of it it will work as a reality check.its training your subconscious to do these things even in your dreams and when the reaction in your dream does not correlate with reality it awakens your mind to the fact you are. Dreaming ...
Dream lucidity is awareness that you are dreaming. This awareness can range from a faint recognition of the fact to a momentous broadening of perspective. Lucid dreams usually occur while a person is in the middle of a normal dream and suddenly realizes that they are dreaming. This is called a dream-initiated lucid dream. A wake-initiated lucid dream occurs when you go from a normal waking state directly into a dream state, with no apparent lapse in consciousness. In either case, the dreams tend to be more bizarre and emotional than regular dreams. Most importantly, you will have at least some ability to control your "dream self" and the surrounding dream.
Keep a dream journal. Keep it close by your bed at night, and write down your dream immediately after waking, or the emotions and sensations you experience right when you wake up. This will train you to remember more of your dreams, which is important for lucid dreaming. [1] Plus, there's not much point in controlling your dreams if you forget the experience before the morning.
Alternatively, keep a recording device by your bed.
You might remember more of your dream if you stay still for a few minutes concentrating on the memory, before you start writing.
Use reality checks frequently. Every few hours during the day, ask yourself "Am I dreaming?" and perform one of the following reality checks. With enough practice, you'll start following the habit in your dreams as well, cluing you in to the fact that you're dreaming.
Read a page of text or the time on a clock, look away, then look back again. In dreams, the text or time will be blurry or nonsensical, or will be different each time you look. [3]
Pinch your nose, close your mouth, and test whether you can still breathe.
Simply look at your hands and feet. These are often distorted in dreams when you inspect them closely.
Repeat "I will be aware that I'm dreaming" each time you fall asleep. Each night as you fall asleep, repeat to yourself "I will know I'm dreaming" or a similar phrase until you drift out of consciousness. This technique is known as Mnemonic Induction to Lucid Dreaming, or MILD. [4] Mnemonic induction just means "using memory aids," or in this case using a rote phrase to turn the awareness of your dreaming into an automatic habit.
Some people like to combine this step with a reality check by staring at their hands for a few minutes before they go to sleep.
Learn to recognize your personal dream signs. Read through your journal regularly and look for recurring "dream signs." These are recurring situations or events that you may notice in your dreams. Become familiar with these, and you may recognize them while you dream, and therefore notice that you're dreaming.
You probably know some of these already. Common dream events include losing your teeth, being chased by something large, or going into public without clothes on.
Drift back to sleep when awakened from a dream. When you wake up and remember your dream, write it down in your dream journal, then close your eyes and focus on the dream. Imagine that you were in the dream, noticed a dream sign or reality check, and realized it was a dream. Hold on to this thought as you drift back to sleep, and you may enter a lucid dream. [5]
Note that most lucid dreams occur while the person is fully asleep, usually because he notices a bizarre event and realizes he's in a dream. This is just an alternate trigger that starts off about 25% of lucid dreams.
Consider purchasing a light alarm. Go online and purchase a light-based, instead of a sound-based alarm, or even a specialized "DreamLight" designed to induce lucid dreaming. Set it for 4.5, 6, or 7 hours after you fall asleep, or set it to go off every hour if possible. While sound, touch, or other stimuli during REM (Rapid Eye Movement) sleep can also make a dreamer aware of the fact he's dreaming, one study shows that light cues are most effective. [7]
You don't want to actually wake yourself up (unless you try the Wake Back to Bed method below). Keep the light alarm more than arm's reach away from your bed, and/or cover it with a sheet to dim the light.
Meditate. Before going to sleep, meditate in a quiet, dark room. Taking a meditation training course may give better results, but to start out, just pay attention to your breathing, or imagine ascending or descending stairs. The goal is to stop thinking and enter a quiet, comfortable state, and from there slip into a lucid dream.
Keep in mind that "Wake Induced" lucid dreams are rarer and more difficult than dreams that become lucid after you're already asleep.
There are many meditation guide videos online specifically designed to help you lucid dream.
