Same thing happened to me with the loud noises and the panic. It then made my OCDs and anxiety A LOT worse, I felt like i'd never recover (even weeks after the bad trip) but guess what, with a bit of knowledge and patience it all went away and I got my life back.

I started smoking again and so far so good. I even had the exact same bad trip a few days ago with the loud noises and the anxiety but I just "enjoyed" it and explored it.
