I was lucid in this dream, although I'm not sure if I was lucid before 'he' came or maybe I realized I was lucid when I first noticed him...?

Anyways I believe I was sitting in my elementary school gym with two younger guys, possibly for babysitting purposes. All the lights were out, save for one in the middle and we were waiting...waiting for something. I glanced over to my left and saw 'him' standing between the younger two, where it was empty only seconds before. He seemed to carry with him a sort of presence, some light around him as well. Physically he appeared human, and I thought he was male but with either I couldn't really be too sure. He was wearing long brown robes similar as in the B.C. era yet they could also pass as something incredibly futuristic. In age he looked 20 or so, yet with the vast wiseness I sensed from him the best way to describe him would be... well, timeless.

I tried to turn my head to look at him straight on but I couldn't move my head past a certain point, it was stuck. I said to him, "Sorry but I can't seem to move my head further to look at you" (something like that). Next the two younger guys got up and ran to the light in the center and I along with them, forgetting the man behind me. As I reached the light I realized I had full mobility throughout my body.

It's probably too early to tell if he's a dream guide, based off one dream alone, but does he sound like he could be one?
