Sometimes I think that nothing is real. Everything exists in perception and the only knowledge available to me is limited to my senses. Colors, textures, sizes - all is perception. Therefore, all I see is my subjective vision.
There are moments when I feel like it is all just a dream or a test, or a theatrical performance and my mind will transform into different materia as soon as I wake up and these filters of sensation come off.
But I also think that i know more than I actually know. You already know something before you find it out. I think that human mind has so much more innate knowledge than what we actually apply.
Over the time I learned to trust my intuition a little more and listen to my inner voice.
