I usually feel very relaxed, but if something upsetting comes to mind, I can get paranoid and freak out (e.g. I walk down the street dreaming off and next to me passes a bus; somehow this makes me think that my father might be in there, even if it's not his usual route, he might see me and notice I'm high) and freaking out feels like a pain in the chest, as if my heart tried to race but couldn't.
My thoughts become very dreamy. When I'm sober and I imagine a story I'd like to write, I see the story played out in my mind like a movie; when I'm high and I do the same thing, it's being played out in a very dreamy way, like in a surrealistic movie. It's wild to experience this. I lose track of time. I feel like I escape out of time with my mind, just flowing to some inner realms where my stoned thoughts take me, and then realize that only 2-3 minutes have passed.
The music perception is so different. I'm able to hear aspects that I never heard before. It sounds more alive and it surrounds me all over. The best thing I ever experienced was listening to The Beatles' Lucy In The Sky With Diamonds while stoned; I felt as if I was in a cathedral and the sound was pouring in arcades all over my being. Hard to explain it logically, but I guess you all know what I mean.
Everything I see seems brand new to me and very interesting. I look at things I've known for a long while and I'm amazed as if I saw them for the first time (and knowing all along that they are very familiar to me). There's poetry in everything I see or hear.
I am more aware of the positive feelings I have towards the people I love. When I do interact with them, even on the phone, I am overwhelmed with how much I love them.
Also, when I'm high I tend to be very open about my drug use, I'm less prone to feel bad, guilty or ashamed about doing drugs. I want to share with the world the wonderful feelings I experience. I tend to forget all the stigma surrounding drug use (which is not a good thing to happen, since last time I was high, I talked to one of my friends on the phone and told her what a great high I was experiencing - and this was happening at the university campus fast-food; luckily, none of my teachers were there).
