I remembered that the black block is something that, in a dream, was left in my vagina after I was raped by a giant red locust or daddy long legs. It was wrapped in red Christmas paper. I heard in the dream "Yeah he left something in you alright."
After the above dream I did not know what the present was, as it was wrapped. Your comment "I am not a good wrapper," even though I did not know what you meant, brought this to mind.
