There's a reason I have a Blue Dream story.
The first time I smoked Blue Dream was just a little after I had gotten my rec. At the dispensary I had gotten two indicas (White Fire 43 and the house) and the Blue (which while technically a hybrid, was sold to me as a sativa). Before, I had only heard great things about. I had friends who loved it, plus the name made it sound, well, dreamy.
My friend (who helped pay for my recc and the flower thereafter so that I could him some, but overall, is a dick) and I were at a cool park, preparing to smoke. The only thing I hadn't tried was the Blue Dream--so obviously, we had to.
We grinded it up, I probably mixed in a little indica, and began our hot box.
The body effects were actually really nice. And I was mellow enough that I was singing loudly to the Vampire Weekend I had playing. My friend even complimented me.
Then came the head-high. My friend and I were talking, and he said something--admittedly--very rude. As a person with OCD, I already think a lot, so the heady effects of the strain kicked it, and it spiraled from there.
I was convinced that no one actually liked me. I was crying. Thinking how people only kept me around for mild entertainment--that otherwise, I was just tolerable (no one hated me, but they didn't like me either).
At one point--I felt like I was watching myself on television as a character in a show, but then suddenly been thrown into her body, and had to deal with the reality of my own existence.
I've felt similarly before (though not identical), variously thinking it was just a thing everyone did, an out-of-body experience, and once I became more psychologically savvy, consider the possibility it could be dissociation. I'm still not entirely sure, but whatever it is, I was flashing inbetween it and reality.
While totally aware of my surroundings, I felt like I was constantly being thrown into my own body--and as I settled in, I was being thrown back in again--like I hadn't been myself the whole time.
I don't think this makes Blue Dream a bad strain--I think it makes it a bad strain for me. And even then, some aspects of it I really appreciated. My own wiring makes Blue Dream a hard high for me, and I'm not sure the good really outweighed the negatives to smoking it.
If you can handle your head-highs, absolutely go for it. It's popular for a reason! But if you're like me, at least don't smoke with a dick.
