I get what you mean... its just a crazy 'head fuck' high, I find them very enjoyable. I only found I got this sort of thing after I used LSD a could of times. Also when I get really stoned I get slight trippyness, its cool.
Also to answer your question, there is two different types of weed; Sativa and Indica, one is very 'buzzy' and happy high, one is more lazy and slow high (I cant remeber which one is which).
