Strange dream

I would like to share a dream I had last night that quite scared me and get some of your opinions if you like :) ,I was falling asleep when, in a state of half-sleep, I began to see white, and from this white, two things appeared, at first like some sort of spheres and then as elongated things, side by side. They didn't seem solid, and their bodies were gray, but not a uniform gray; rather, some spots were darker and others lighter. After a short while, the one on the right disappeared, and only the one on the left remained. Suddenly, the white vanished, and I began to have a blurred vision of what seemed like my room. As I turned my gaze, I saw something I can't describe, surrounded by a white halo. Right after that, I started to dream normally.
