In the beginning of the practice, it’s usual to fall asleep. As a result of
our busy lives, our bodies are conditioned to respond to relaxation with sleep. But as you keep practicing, you will be able to relax
your body, while keeping your mind perfectly aware. If/when you fall asleep, probably that is what you need the most in that moment. Just trust yourself and try again.
Unfortunatly deep states of self hypnosis, where we experience such as lucid dreaming, deep meditation, vivid visualizations, among others, is not reachable to the majority of us, without a considerable amount of time of practice. But keep trying, you deserve it!
