Not “ego-less” but “viscerally knowing my ego isn’t in charge of what it thinks it’s in charge of”. I’m also not confident that this was the same thing as stream-entry/enlightened/etc.
For what it’s worth, as I model the path, I’d guess that this was stream entry. That is, you had insight into the non-separateness of self for the first time. It’s expected that it doesn’t stick, as only rarely does that happen (very, very few people seem to experience sudden, persistent awakening), but it gave you a taste of it, and with dedicated practice it can become persistent, but it general requires having a string of insights over months and years that resolve various confusions that stand in the way of persistence.
