Memory Tombstone

Dark, black blindness 
So I may view nothing 
Of the rose on the sill 
Episodic shots of streetlight 
Make features of a face 
Senses dampened madness 
In mirages of blackness 
Eclipsed on greyed matter 
Collected in crazed shadows 
Thoughts are my secrets 
Tears are mine alone 
Church bells in distant song 
Call to my memory tombstone 
In eviled devilled undertones 
That whisper as I sleep 
Which tombstone turns? 
In the peril of my hearts call 
To speak to haunt 
To mock my weakness 
Tomorrow I fear 
The haunting of my 
Memory tombstone

Rita Pal's questions:

I tried to obtain a dark effect for this poem. Its about the haunting of a person by past memories much like apparitions after death. Is this conveyed to the reader?
