Interesting. You said that you were scared but didn't panic, doesn't that mean you were sort of 'calm'?
Also I think a few other people may have mentioned it, but if you ever try marijuana again, I've heard that indica is more relaxing than Sativa. Sativa is more of a stimulant. Of course I've never smoked so I have no experience, but from lots of research most people say if they want to relax they go with indica strains.
I quickly found an article that explains the difference between the two strains pretty well, if you are interested.
