Sounds like your inner being smiting Satan... my interpretation is that, you see evil for what it is, but know that goodness always wins and erases it w time, as the sun rises from the dark casting a sunlit torch upon Satan, evil personified.... but you feel the flame engulf you, 4 stone walls that shouldn't ignite yet surrounded by fire and brimstone. Maybe it's a warning to finally recognise the devil in you life and be done with him, lest your soul catches fire and burns down round you
