Can prayer change reality?

I may have mentioned before that one of my hobbies is listening to NDEs (near death experiences) on Youtube.  Mostly I consider it entertainment to pass the time when I am doing some boring mindless task. I don't view these accounts as holy writ or anything, but once in a while they lead to some insights. 

I find that all the accounts are different, but they all have some things in common. Those would be, a cessation of pain, a sense of profound peace and love, taking place outside of time. The narrators mention meeting a being of light, sometimes calling this entity God, or Jesus, or saying that it is an angel. I am aware that there are some unpleasant NDEs, but I don't go looking for those. I assume there must be a reason for them, but most of the accounts are positive.

Anyway, the latest NDE I listened to was this one:  I Saw How Prayer Actually Changes Reality (NDE)

The narrator was a woman who identified herself as Alice Carter.  She said she had been injured in a bad car wreck caused by a semi driver who fell asleep on the road and crossed the center line.  She was taken to a hospital and the doctors said that she had been clinically dead at one point for over 7 minutes.  

Following is a summary of her account:

She entered what she called a space between spaces, a dimension of pure consciousness. She met a being of light, who introduced themselves as "Gabriel".  She doesn't say that this being was *the* Gabriel, the archangel, or that they were an angel at all. They showed Alice a tapestry of light, with each thread being a prayer being said somewhere. The prayers weren't just words, but actual streams of energy. Some were like laser beams, others were softer. She was shown how prayer interfaces with reality. It isn't just asking for things, it is actually taking part in the creative force of the universe. she was shown that multiple people praying for the same intention amplify each other, a resonance pattern.  

Gabriel showed her a group of people praying for peace in a specific instance, and that a stream of white light was influencing people in that area. That the prayers literally altered brain chemistry reducing aggression and increasing empathy.  He showed her a kind of spiritual DNA pattern that was the pattern of all possible answers to any given prayer.  Prayer doesn't change God's mind, but changes what is possible in the framework of free will and divine law. 

Less effective prayers came from a place of self focus, or lack of regard for God's will. More effective ones came from a place of love, and faith, and a desire to align oneself with God's will.

What was fascinating to me was Gabriel saying that there was a repository of prayer, that the energy didn't just disappear, that every prayer ever said  still existed. That even prayers said hundreds of years ago still influenced events today. He told Alice that the prayers of her great grandmother, who died before she was born, were influencing outcomes in her life.  Which kind of squares with our belief in the Communion of Saints.

Alice was shown that every prayer creates lines of light that form a beautiful web around the planet. Gabriel told her that each prayer participates in the act of creation. He said, "Tell them that their prayer matters more than they think."

The video is about 16 minutes long, like I say, I take these things with a grain of salt, but I just thought it was fascinating.  And was more interesting than cleaning up the refrigerator.
