Welcome to the Nexus; I hope to have some interesting discussions with you in the future if you're up for it.  I myself graduated Cum Laude with a Bachelor's degree in Behavioral Neuroscience in May and am currently working in a cabinet factory where I build roughly $100,000 worth of cabinets each night (you can buy them at Home Depot).  When I was working in the finish room the person wiping stain next to me was also a college graduate.  Good luck with your neuropharmacology endeavors, the brain can be an extraordinarily useful device whenever it knows what to do.

Or maybe those beings are a figment of our imagination and we are really talking to ourselves.  But this doesn't mean you can't learn anything by listening to your inner self; even the product of imaginary forces can have a real world influence (remember from math that i^4=1).
