Is it normal to have a trip this bad?

Yesterday, I was smoking alone. I got high to a point where I wasn't really thinking about what I was doing and forgot to breathe some in between hits(was in a rush). I smoked a bowl by myself(which usually doesn't bother me). But something went really wrong. I didn't even think I was high, but after I took one more hit, I immediately felt it. It felt like someone was grabbing my eardrums and putting intense pressure on them. I heard this INSANELY loud ringing noise in my ears. I couldn't grab anything because I lost the energy to. I literally fell into this huge pile of leaves in my yard and didn't get up for at least 10 minutes. The ringing was so intense still that I felt like crying. Once I finally realized I had fallen down, I stood up. I was very dizzy and felt horrible. To top it all off, a fucking SNAKE came up behind me and slithered away. I was so drained of energy that my brain barely registered what happened and I couldn't run! I couldn't hardly walk back in the house! It was horrible. Is this normal? I have been smoking for about 3 years now and this has NEVER happened.
