There are many methods available that promote the occurrence of a lucid dream.
Eating specific food (otherwise known as "lucid nutrition") before sleeping is one of the most successful methods to induce them.
This is a list of the best three lucid foods and liquids to intake.
To achieve the best possible results, remember to eat or drink immediately before sleeping.
Orange Juice Orange juice, or any other pure fruit juice with no additives keeps your nervous system active while your body's muscles relax.
Drinking a full glass of juice will allow for more vivid and memorable dreams, ultimately increasing the chance of a lucid dream.
Milk and Cheese While it is known that milk and cheese (or any other dairy food) can help your body rest, they also greatly improve your dreams.
Milk and cheese contain amino acids which have been proven to stimulate the production of a vital neurotransmitter for sleeping and dreaming, melatonin.
Mustard Various sources have reported that eating a tablespoon of mustard will promote a higher success rate for lucid dreams.
It may take up to three attempts for it to be successful, so it's important to remain patient if the method repeatedly fails.
Other foods include pickles, ice cream, popcorn and fish.
While they are not as successful as the three foods and drinks listed above, some have suggested that they will improve your overall dream memorability and "train" your brain for future, naturally triggered lucid dreams.
However, their use immediately before sleeping is not recommended as they contain fatty acids, salts and sugars which certainly doesn't help getting a good night's rest.
