Yesterday my high made me freek out and even if I wasn't high, it would of still been some of the scariest stuff I've ever seen, on or off, just weed. I was outside during a freeky storm with rain, hail, and wind that got faster and faster to the point I could barely walk, and all in under 2 minutes. We were high so we decided to sit in the middle of a field the whole time till it passed. The clouds were moving faster than I've ever seen, and I didn't notice them till my friend pointed at them, and freeked. The sky went almost pitch black too, almost like a movie. 2 minutes later after sitting down in the storm I decided it was getting to bad, to fast, to stay where we were. So we left and I barely made it home, and not sure if he made it home safely. The hail that came halfway walking back home was intense. It took away my high feeling pretty much, until I got home through the wind. Which took at least 10 minutes longer than my regular 5 minute trip back home. Once I got home I tried sleeping cause I couldn't breath and stop laughing. That was as scary as sitting and walking through the storm.
I did almost the same shit a few years ago. Me and two friends went out to smoke and got locked out in the middle of the night. It started pouring rain like crazy and lightning began to strike closer and closer to us. We were all really stoned we had smoked about a quarter between us and running through a field to get to a shelter. Being stoned made it incredible. The thunder sounded even more menacing, it was so loud I could feel the soundwaves hit my body like a subwoofer and the lightning would light up the field we were in as bright as day for a split second. I wish we had hail too.
Why didn't you just go inside? But I definitely can relate (not about the freaking out), but something like seeing the clouds move really fast... it can sort of blow your mind. Normally when its storming I don't even think about it, but when I'm high, I REALLY think about it. Like I think about how theres a huge mass of water just falling out of the sky, or how the air above me is filled with static electricity, and I'll kind of feel at one with the storm. Which is actually the sort of stuff I find most appealing about strong pot.
OP I checked your location and I live quite close to you so I got hit by the same storm. It was fucking vicious. Hail was powerful enough to crack my windshield and bust one of my wipers.
