Taken onto craft as a child, greeted by NHI

When I was a child and was taken through my window onto a craft by Nhi. When I was inside there was a very open space where about 8 – 10 beings of various species were waiting for me to arrive. They all stood together watching me as I walked up to them and seemed happy to see me, I felt a very welcoming energy. Unfortunately, as soon as I approached them, I was unable to recall anything else, and the memory goes blank. They were all humanoid and had various colors of skin that were not of human nature like blue. I can barely recall what they looked like or the craft since it was so long ago but then energy they presented as I was guided to greet them has stuck with me for a lifetime. I've wondered who are they, what did I do that night I couldn't remember and will they ever some back? Had some of the beings I have encountered through my life been there that day?
