yea almost the same thing happned to me last night. i smoked a bowl from the bottom of one of my lb jars and it was like pure keif i got sooo stoned it was like someting was pushing on my whole body and i actualy had the same breathing thing i like almost stoped (i probaly dident it just felt such) it was actualy very nice i had lots of fun ^^ but it was kinda scary at the same time. btw i am a regular user so it couldent be a tolerance thig i think its just a really good weed and a certan mindset.
peace
