Question about sigil

Had a dream last night, of waking up in bed from a dream…weird yes but done it before. In the dream–the one I woke up from there were blue lights on my wall. Like dots except maybe the size of marbles. 4 or 5 of them like light coming from a window but no window in the room.

Then a circle appeared on the wall, bright white but drawn in black. I’m no artist so I will attach a quick paint program drawing. Has anyone seen a sigil similar to this or can anyone help me understand it?

the also attached Lion picture I found online it was similar to except sideways and no wings and no mane
