A Ghost from the Past

The 13th each month he appears.
 I lie in my bed, I can sense him.
 The ghost from my past brings
 A wind from the cold well of souls.
 Lost in the midnight of illusion,
 An entity's intrusion;
 Peculiar, undefined.
 Scarred of these eerie visits,
 A bestial advertise.
 Now you know there is no turning back
 Are the ghost whispering words from the past.
 I've traveled for thousands of years.
 I'm hoping you finally will bring me home.
 Break puzzles of spells
 And these trespassing nights reach the end!
 Lost in the midnight of illusion,
 An entity's intrusion;
 Peculiar, undefined.
 If you see me don't turn away&
 Do identify me with your own soul!
 In this conundrum you have the parts.
 You have to dare the puzzle through.
 I will explain
 Why I remain.
 I will search the night
 Until your final denial's over
 Scarred of these eerie visits,
 A bestial advertise.
 Now you know there is no turning back
 Are the ghost whispering words from the past.
