The Short Answer
Ok, this is only a guess (until other, more knowledgable people answer your question), but first to clarify: your vision fading after standing up too quickly is due to low blood pressure, not lack of air. I think perhaps much of the euphoric feeling is actually just adrenaline in response to your body being worried about what's going on. Same reason people get a rush on roller coasters or watching horror movies, for instance. Our bodies know that if we are losing air, it's likely not because we are dumb and don't know to avoid it, it's because we need more energy and ability to get out of a scary situation, hence adrenaline. Additionally, getting oxygen after being deprived of it can feel incredibly relieving, which might be where the "high" comes from, in addition to the adrenaline.
