For example, when I was a pretty strong Christian during church I would feel a very strong deep passion or love or something run through me through specific moments during the service. I went to a Christian camp where we had huge bonfires with 50 or so kids and lots of staff on hand. It was so moving that it would bring some of us to tears. What really shook me though is that I started to notice the exact same goose bump inducing feeling from non-religious events. When watching really passionate movies for example in a very crowded theatre I would feel that same deep feeling at deeply emotional points in the movie.
I'm convince that God's Holy Spirit rarely, if ever, works on people in large groups as a part of a religious services in Catholic/Protestant churches. However, some individuals who are in these type of churches who are experiencing the Holy Spirit are being directed out of those churches and practices. You also must consider that just as God has a Spirit He uses to influence people so does Satan have a spirit he uses on people. What Satan does is use his spirit power to support false religion. A good example of what I'm talking about is Easter. Satan's spirit will work to support Easter practices. In the video about this below notice how deceptive Satan can be.

As to the specific feelings I felt while alone I’ve felt those exact same feelings when deep in meditation. I think prayer combined with our longing to be “one with the creator” causes our brains to slip into a meditative or Theta state. When in this state it’s easy for me to see where someone may speak in tongues, hear the voice of God and feeling his presence even if all of that is complete nonsense. Deep meditation can have a very powerful effect on the brain.
Sure this can happen, but God can give you much stronger experience. What He usually does is help you meditate on the scriptures so you can get that deeper meaning.
Richard Dawkins is always pushing Religion as being a harm and trying to exclude it at all costs. A Fundamentalist Religious person in my books would do the same about all other religions as well as non-religions. Ultimately both sides are excluding anything but their own world view. They are the same.
It’s fine to practice a closed belief system but it will not help further society. It will exclude you from social growth as growth involves change and change is not welcome in a Fundamentalist Belief System (like Dawkins or New Earth Creationists / Many Evangelicals).
I tend to lump atheism, scientism and false religion into the same category - being Satan's destructive influence on the world. I also don't see growth in the knowledge of the world to be important. Much worldly knowledge is bad. I must make careful distinction between technical knowledge and knowledge of the Word of God. I always think of Erich Fromm's statement in
The Revolution of Hope: Toward a Humanized Technology set forth below about man's unguided use of technical knowledge.
“In the search for scientific truth, man came across knowledge that he could use for the domination of nature. He had tremendous success. But in the one-sided emphasis on technique and material consumption, man lost touch with himself, with life. Having lost religious faith and the humanistic values bound up with it, he concentrated on technical and material values and lost the capacity for deep emotional experiences, for the joy and sadness that accompany them. The machine he built became so powerful that it developed its own program, which now determines man's own thinking.”
