But it wasn't that cool at all. I thought I was dieing for a while, or at least I wanted to die because it was scary.

Recently, like 3 days ago, I was around some second-hand marijuana smoke and I felt slightly like that, but not enough to freak out.
It sounds like you just smoked quite a bit of MJ and you got too high too fast, and you got a bit paranoid. Even if you were allergic to marijuana, it would still affect your brain in the same way. Your skin would probably itch, your throat may swell up and you would have difficulty breathing, your eyes would water and itch, your throat would be kinda scratchy etc..
