Last night’s lucid dream:
I become lucid while standing behind the trunk of a red dream hatchback car. The old car looks kind of like the one I had sold a while ago. It has a large back-window pane. I know exactly that I am dreaming.
I tap with my index finger against the glass and feel the resistance of the window glass. My intention is to stick my finger through the glass and am surprised that it has such a resistance to my tapping, especially since I have succeeded many times before in other lucid dreams to stick my fingers through dream materials…
I say smirkingly to my dream-self: “I know exactly that this is a dream. This glass is my mind. This glass does not exist, it is only in my mind.”
After intial resistance, after the second or third tapping, the glass becomes soft and my finger and hand dive through the window pane.
I follow through with my entire body and I end up in the interior of the car where I examine the details.
After a few seconds I wake up.
…
In the waking up process between dreaming and waking the following realisation came up, which I recorded with the voice recorder:
Reviewing this recent lucid dream experience - being able to put my finger and hand through the initially “solid” glass window of the dream car with its initial resistance and rigidity and finally overcoming it - I realize that it is a perfect example of the emptiness of mental phenomena:
There is no difference between the nature of resistance to/of the dream car glass and the nature of resistance to any mental phenomena in the waking world - such as, for example aversion towards certain tasks at work during the day.
They are all pure mental constructs. All mental constructs are ultimately empty. Like the window glass.
This experience is a vivid example of the nature of emptiness. Breaking through or dissolving the rigidity is an example of starting to understand the nature of empty phenomena. All mental phenomena are empty. The rigidity - any constrictive quality - is an illusion.
