This particular thread opened my eyes to my historical encounters with the herb.
When I was a boy in my late teens and the herb began to go mainstream we almost exclusively got "Mexican" which meant seedy oz./$15.
This was light weight, fun, conversational herb.
Based on what I've read here probably sativa (native to the Americas?).
After the Army I moved to Madison WI.
In the early to mid 70's Colombian killed the market for Mexican.
The Colombian we got was browner than the Mexican, much more of a couch lock effect.
Based on this thread I'm guessing the Colombian was Indica.
Two outliers I fondly remember were tai stick and Oxacan.
Tai stick was borderline psychedelic, I'm guessing Indica.
Oxacan was a bright (almost neon) green and got you outgoing and up - I'm guessing sativa.
You got 'em backwards. This is how I remember it: sativa cerebral, indica inside you.
Sativa is the Mexican, Thai, and Oaxacan from your description. Borderline psychedelic, conversational, "fun," outgoing. Sativas tend to have a cannabinoid ratio that's higher in THC and lower in CBD.
Indica is the stone. Body feels like gravity times a hundred, munchies for days. Falling asleep on the couch halfway through the movie. Colombian sounds like it was indica, so it had higher CBD and lower THC ratios.
All these strains I have access to today are awesome but sometimes I really wish I could go back in time and grab a couple pounds (probably for $100 or so LOL) and sample the offerings of the day.
