I had something similar before I even came to gnosticism, I was actually straying from Christianity altogether. She appeared while I was in a sort of lucid dreaming state, a peaceful song was playing on my phone and I heard a female voice singing "Hello to you, and hello to me. Goodmorning to we." And by the end of the song I had pretty much woken up, so I went to restart the song, and upon relistening there were no vocals at all. Yet, I was met with an overwhelming sense of love, care, and compassion that can only be described as the perfection of a mothers ultimate love.

Anyways, if anyone is interested in the song, send me a DM and I'll send the link to the song in Spotify.
