When people go on and on about how powerful a medicine oral DMT is, they are probably under exaggerating. There has never been a substance that has broken my self down so much as oral DMT has to me.
I absolutely have to stay in my bed for the most of it and I often get lost in my house whenever I leave my bed because my mind is so beyond processing simple ideas without falling into infinite warps of patterns and emptiness. My visual field does the same thing as well.
In fact on a good oral DMT trip there is no difference between the 'mindfuck' and the visuals, its all melded into one thing which is some weird elusive concept that I have forgotten about.
