Altered states of consciousness seem to be a common aspect to religion. Sometimes religion attracts believers due to promises about the afterlife or by simply being the cultural status quo, but other times, powerful subjective experiences lead a person to convert to a religion or stay with a religion.
The nature of these types of experience seem to differ substantially from person to person, and seem to be brought on by various ways from prayer, or meditation, or dancing, or substances, or rituals, or hypnosis, or trauma, or out of nowhere. Some of them are measurable. Some of them can occur to non-religious people as well. They seem to occur to people of various levels of intelligence, knowledge, cultural background, personality type, etc. They also seem to have occurred stretching far back into prehistory.
Altered states of consciousness are a foreign concept to me, except for the standard sleep vs. wakefulness cycle. I don't really understand altered states of consciousness, apart from reading scientific literature, but it does seem that a majority of people have had some type of this at some point.
Have you experienced any sort of religious or secular altered state of consciousness, like a mystical experience, or union with deities, or hypnosis, or a trance of some sort? If so, for what purpose did you seek it (if you sought it at all), what was it like, is it replicable, and in what way do you interpret it?

Sure, plenty of times. I've done various kinds of Kabbalistic meditation to achieve trance states (with several notable successes), and when I was younger, I did three vision quests with the aid of fasting purification and natural hallucinogens.
In the vision quests, the one that was strongest, and had the most "visions" was the one I did with a combo of mescaline and opium. Some amazing visions, very intense, and it was the one I did with most intent of seeking. At that time in my life I was not observing Judaism, and was trying to decide what I should be, how I should structure my life in terms of a framework of spiritual development and moral behavior. I vision quested with the aim in mind of seeking answers to those questions. I didn't really find any final answers, but it cleared a lot of things up for me, even just in terms of what to avoid. My friend and I fasted for three days, went out to the wilderness, took the peyote, smoked the opium, and tripped hard. It was definitely one of the times I really felt like I wasn't just enjoying some mental special effects, but that (as Huxley put it) the doors of perception had opened, and I was able to interact with the world at a different level, and seek wisdom from supernatural sources.
I don't feel comfortable sharing more specific details about that one, though you can PM me if you're really interested.
The other two vision quests were with the aid of some very potent shrooms and a little good weed. These were way less intense, but were very helpful. One was in the countryside, one in town, both with the same friend, with the aim of trying to get any kind of sense of the energy of the divine in the world.
I felt an incredible sense of connection to everything. It was an amazing sense of comprehending how everything, living and nonliving, was joined by the thread of a common energy that whispered through the world like a pulse beat, and at the same time understanding that what I felt was the merest shadow, the most surface of shallow beginnings, of what really underlay the universe as we usually perceive it. It was like pulling back a curtain enough to see the shadow cast by someone standing on the other side, enough of a shadow to realize that they were absolutely huge. And yet I felt something that transcended the usual euphoria of such trips: a sense of being loved, of being touched by tolerant amusement and affection. I felt like I could sense that God knew what I was doing, and appreciated the sentiment, in the way that we are both amused by and appreciative of sometimes reckless childish enthusiasm in the very young.
The Kabbalistic meditation came much later, after considerable growth and study on my part, and without the aid of substances. Unless you count light fasting and trance music as a substance. I use a free-flowing combination of pranayama breath work, Kabbalistic mantra meditation, and deep visualization. Mostly I do it for inner peace and balance, but if I go long enough, I can usually make it to a light trance state. What I've perceived using this method has been different at different times, but it is always a sense of joyful closeness, of perceiving the warmth of divine presence as though separated by just a light screen or curtain. And as for the rest of what I perceived, I'm not sure I can put that into English words: it needs the language of Kabbalah.
But, again, I'm happy to try and go into more detail if you like.
