To start off, a Sigil is a picture that stands for what you want to do.
In the Sigil-Induced Lucid Dreaming technique, you get the Sigil to stand for your intention to have Lucid Dreams.
This is done by taking your intention and turning it into a sentence like “I will have a Lucid Dream.” Afterwards, you need to put it in picture form, so you take the individual letters and make them into a small picture that you can easily visualize. Just take some of the letters and make a doodle.
Next you imagine your picture in a focused state of mind so your Subconscious gets the message.
Lastly, you destroy the picture and forget about it so you don’t end up trying too hard.
Your Subconscious will allow you to realize that you are dreaming without you having to do a thing.
