Is it normal that this happend when i smoked?

I smoked some incense maybe a week ago. It was called cloud 9. Anyways, I smoked it in a pipe and after 2 hits, I was blown, and I walked inside and sat on the couch for about a solid 2 and a half hours before my friend ( who smoked with me and his high had worn off) had picked me up off the couch and gave me water. He told me I had been just sitting there emotionless, unresponsive to his words. I could here everything he said, and thought I was answering him, guess not lol. Bout 5-10 minutes of standing up, I was like "dude, I'm bout to throw up" he took me to the bathroom where I stayed fore about another 2 hours throwing up. An the whole time I was sitting on the couch I was halucinating like a mother fucker. When he picked me up, it brought me back to my senses. Then I went to the bathroom here I faded in and out of halucinations and the real world. Lol, I got so close to the toilet water that when I threw up, it got of my face hahaha. In the very back part of my mind, underneath all of the halucinations, I knew this was a high, but couldn't keep my senses together with out someone touching me. So I was high for a total of about 4-4 and a half hours. Is this normal that incense went down like this? Oh! And this was my second time smoking incense, first time it wasn't like this.
