Sativas should give the smoker a cerebral high.The more potent the sativa, the more head high one gets. Sometimes to the point of light tripping. If you are fortunate enough to get your hands on one of the top of the line hazes, you will know what I mean. It sounds as though you got a hold of a very potent haze or something like C99, Apollo 11, Jack Herrer, Kali Mist, Skunk #1; etc. A good indica will glue you to the couch with it's powerful body stone. A potent one will just reach inside your chest and grab you! A good mix with give you both body and cerbral highs, just not too much of one or the other. Hope this helps clear things up for you! Take care and be well....
