Cannabis can bring out latent psychological problems in individuals. This could have, possibly, occured for you.

Also, time distortion is normal with cannabis consumption. While I have never experience nor heard of it being as pronounced as your experience, I guess it may be possible for it to occur that prominently.

Anyways, if you do choose to venture into it again, have someone with you, a "trip sitter", to watch you and make sure you're OK. If the symptoms occur with each smoke, stop smoking. It may be just from the first experiences, but no one can be sure at this point.

Whatever you choose to do, good luck, and I hope it goes well.
