I dream a dream

I had a really strange dream last night, I dreamt about my grandmother (she died over 2 years ago) and it was the first time that I've ever dreamt about her (well knowingly) and remembering all the details. Basically I was in her old home in her kitchen, I pulled out a middle drawer and it was just filled with envelopes all sealed but addressed to me, I opened one and in it contained A4 letters, all handwritten in her writing, I then started crying, reading the letters - I can't remember word for word what they said, but along the lines of "I'm so sorry it has taken so long to contact you" and "I have tried so hard to get through" it was really telling and in another part of the dream, my grandmother and I were walking in the glorious sunshine, she walking with a wooden stick (she did own one but never used it) and she leads me to an alleyway and on the side is a small patch of grass, in the middle it looks like one of those ponds that someone's filled in and its overgrown with grass, but it was neat and it had remnants of stones built in and she stops and circles the area with her wooden stick and looks at me and smiles. Then I woke up...weird huh?
