I've been having dreams of my late-grandmother who died this past March from health complications and some form of dementia. I always called it Alzheimer's but I don't think that was what she officially was diagnosed with.
Anyway, since her death, she has been visiting me in my subconscious.
The first time was right before I saw her at the wake.
In subsequent dreams, she is her old, still-lucid self - before she had dementia. She would say something to me.
Her messages were usually cryptic.
All I know is after I woke up from the last dream I had of her (where she hands me a jacket), I started balling like a baby. I still cry when I tell people about it.
