Yesterday I smoked 4 bowls (a 1/4" torque wrench socket) out of a homemade water bottle bong. First I smoked two and then after watching Pineapple Express I smoked another two. I've smoked marijuana 4 times before this, and each time I really didn't get that high, just relaxed. This time after the first 2 bowls and after inhaling as deep as possible and keeping the smoke in my lungs as long as possible I felt quite high, and then after the last two bowls things started to get REALLY scary. Everything began to go in slow motion and after putting my head down for about 1 minute I got up and felt like I was in a dream and that I was trapped. I didn't know how I got to where I was and I felt like I would go out of my body every couple of minutes. Of course my eyes were as red as **** and my heart was beating like crazy. Since I've never gotten this high before, I panicked. This feeling continued for about an hour at which point I just sat infront of my computer for another two, because everytime I moved fast I would get that weird out-of-body feeling again.
What I'm wondering is if this is a normal thing to feel; did I smoke TOO much weed or is this considered a "Bad trip" considerig the fact that I was tripping b***s and that I was extremely tired after being up for almost 24 hours. Is it the fact that I was smoking Indica in the past and I didn't know it and that this is the first time I smoked Sativa?

Here's a picture of the weed I smoked: http://i171.photobucket.com/albums/u...7090108a-1.jpg
It smells really good by the way. It has a kind of sweet herbal smell.
