I think the anxiety would keep you awake and thus be a issue. This is a experience I was planning on putting into the book of my journeys :
A Slumber to Remember
It occurred to me one day that the brain has a entirely different chemistry when one is asleep. I chose to take advantage of this and see what I could experience while my mind was still swimming in this chemical concoction. I set my alarm for the middle of my sleep cycle laying a preloaded bowl of changa at the nightstand. I would wake up hit the bowl hit the recorder as I was sure I would not remember it went I drifted back off to sleep.
As I fell asleep my mind was focused on the experiment at hand and the dreams I had before the journey reflected this. I had spent the day writing poetry and as usual on these days I had gotten to the point of thinking poetically. It is a strange disturbance in the mind when one thinks in a different form that he is used to. It is often something that cannot be turned off even in dreams rhyme seems to take a dominant role.
The alarm shrieked me awake. It hurt my head and at the moment I had second thoughts as to if this was the night that I should try this experiment. DMT is hard enough to handle to use it while still half asleep was just asking for trouble.
As the spice hit me my body felt fuzzy and undefined. I delved deeper into the psyche the dreams I was undertaking just a few minutes ago came back to me clear and sharp. It was a instant replay I saw the symbols and shapes I knew their meaning and what my subconscious was trying to communicate to me.
I looked upon all those who were in my life friends, family, and enemies. I saw them as projections of aspects of myself. Giving me the opportunity to explore facets of my being deeper. I felt that I was living 6.7 billion lives all at the same time a unity of being. I was the human race and it was me each person an aspect of my own persona.
Wars were battles of my thoughts. The dead memories played out. The newborn ideas of new possibilities. Fractals emerged as I closed my eyes undulation splitting off and seeding new fractals. Each separation like a cell multiplying in my mind. I could feel the neurons fire in my brain. Taste the alkaline electrical flow from one hemisphere to another. I chose to focus on my visual cortex and in the dark my mind became illuminated so bright as to wash out the detail.
The darkness of the room began to take back over. I took another hit to perpetuate the experience. I rolled over in the bed and faced down. I felt as if I were floating on a sea then I began to sink. The pressure of the water bore down upon me deeper and deeper I descended. Timeless as a relic lost in the past I felt the solid ocean floor. The covers felt as if they were made of sand I pulled them over me and sunk deep into the earth’s core. The heat generated purged my body of all that was not true. An orange yellow magma like color burned into my eyes. There was no pain no suffering just a cleansing effect.
As I drifted back into sleep I wondered if I would wake. I was not concerned if I would I had no cares no worries. I slept well the next morning rising from a well rested sleep. It was a pleasant journey that I would undertake several more times exploring the space and stars between.
If you don't sin, Jesus died for nothing.
