Do you know anything about demons? [Spirituality & Religion]

Today I had a vision like of a fire spirit thing and then I told it to move and turned into this demon thing with layers of sharp teeth and it was getting sucked in a wall and it was full of shadows and the wall was like black and the wal stoped moving and you could see demon stuck in wall screaming the demon had a narrow face small horns in an s shape. What does this mean who visited me? Why?
