My response to someone's mystical experience of "heaven"

Once in a while someone emails me a description of a marvelous mystical experience they've had. Usually the person is a devotee of the organization I belonged to for about 35 years -- Radha Soami Satsang Beas (RSSB).
RSSB is led by a guru who is considered to be God in human form, in much the same way as Jesus is viewed by Christians. Except, the guru is alive. Once initiated by the guru, supposedly he places his "radiant form" within the disciple's consciousness.
Then the radiant form leads the mind/soul of the disciple through various higher stages of reality until they reach Sach Khand (roughly, heaven) together. At least, that's the way it is supposed to work. Demonstrable evidence of this actually happening is, charitably, slim.
More accurately, I'd say, non-existent.
Still, there are quite a few personal tales like the one below. I'm assuming the person who contacted me is fine with his experience being shared since he speaks of "wanting to give non-believers a different perspective."

By and large I agree with what Sam Harris said in his critique of Eben Alexander's claim that he almost died and went to heaven.
So I also generally assume that when someone shares a profound mystical experience, he or she actually had the subjective perceptions, feelings, and such being described. But this is a long way from what the person wants me and others to believe about the experience.
Namely, (1) that it reflects objective truths about reality that exist outside of the person's brain/mind, and (2) is an experience that should be as meaningful to others as it was to the person.
Regarding (1), lots of people have described their experiences of seemingly supernatural realms beyond the physical. For example, a brief bit of Googling led me to a Jesus Evidence web site containing some detailed descriptions of heavenly encounters.
So are we supposed to believe all of these many varieties of spiritual/mystical experiences, some of them, none of them? My view is, none of them, unless there is convincing evidence that what a person experienced points to hitherto unknown truths about objective reality.
Dreams can seem real while we're having them. So can hallucinations. Ditto with drug-induced visions. The brain/mind frequently conjure up subjective sensations and perceptions that don't exist outside of a person's cranium.
Again, though, this doesn't take away from the reality of the experience as experienced by the experiencer.  As you can read below, the person who contacted me is convinced that he had a blissful vision of the guru and supernatural realms.
Which leads to the second issue: whether anyone else should view a mystical experience as deeply meaningful. Put differently, if another person had the same experience (leaving aside the question of whether it is subjectively or objectively true), would it seem as profound to them?
I suspect not.
I say this based on a lifetime of having people tell me things like, "You've got to see this TV show; you'll love it!" After which I watch it, and don't love it at all. Same is true in reverse, of course. I enjoy things that other people find distasteful.
Riding a motorcycle or scooter, for example; this makes me profoundly happy, while the few times I got my wife to ride with me, she hated the experience.
Now, I think that if I had experiences like those described below -- in a dream, say -- I'd find them enjoyable and interesting. But there's no way to know whether they'd be as meaningful to me as they were to the person who emailed me.
Since I don't believe in the divinity of Jesus, having a vision of him probably wouldn't mean a whole lot to me. But to a Christian, likely it'd be a Wow! experience.
Thus my reaction to the description below basically is:
It's great, guy, that you had such an enjoyable experience. Hope you can understand why, without solid evidence, I can't believe that this is anything but your personal subjective experience, not a reflection of objective reality. It was deeply meaningful to you, but you're you, and everyone else is who they are.
Here's the message I got:
