No, MDMA will give you exactly the opposite effect. It will encourage and cement connections to culture/s and social bonds. It just effects your serotonin, dopamine, and norepinephrine levels. What magic mushrooms (and other psychedelics like LSD) do is increase the communication between distant parts of the brain that don't normally communicate. That will lead you away from consensus reality, not deeper into it.
Not necessarily. MDMA could potentially enable you loose any feeling of self-concern -- no fear, insecurity and self-consciousness; that feeling of being 5 year old on the Christmas morning.
This might be especially beneficial for someone who is communicating predominantly w/ machines since a kid, and who might have trouble empathizing or relating w/ people.
In this short video Sam Harris describes it very eloquently.
