Very interesting that you bring attention to lack of dreams in relation to caffeine consumption.

 I am a life long coffee addict, addict in general. I understand addiction.  Substances like alcohol and coffee are pushed on society because they have a negative impact and a stunting effect on the subconscious and over soul. Sure, coffee does the job. It wakes us when we need a boost. 

Have you ever smoked DMT?

I strive for and mostly fruit, but all herb diet, mostly vines and plant medicines. 

Nevertheless, I've noticed a substantial difference in consciousness during offset lapses of coffee, mostly in the dream world. 

Chill on...
