Is it normal that I enter dissociation every time I smoke weed?

I don't know what to tell you because this is exactly what started happening to me. I used to be able to have a good ole time and then one day I just started getting paranoid and every since then I have been. I mean it don't make me utterly freak its more of an anxiety thing and I get quiet. So I just don't smoke anymore lol maby ill try again in a year or so.
