Letter sealed with wax

To make up for the missing post related to grandpa, here's the dream that I had a month or two ago:

Dream: Sealed

Was in some kind of a small library room where grandpa said he was leaving.

I knew that for years he had contemplated on whether or not to write a book on his past. He always stopped writing, thinking that these are the horrors of the past, and nobody needs to re-experience them.

The next moment I was holding a wax sealed letter, really sad (crying) and disappointed. Instead of opening it, I folded the letter and poured it over with wax. Ended up with a wax cube that had the letter buried deep inside somewhere.
