Someone please interpret my dreams.?

About roughly a month ago my husband's best friend passed away. They had been best friends since they were 8, one could say they were like brothers from another mother. Anyway, since then I keep dreaming that my husband dies in my dream and his bestfriend is "still alive". The first time I dreamt this, I dreamt that my husband was in the casket and everythin was the other way around, his best friend was ballin out crying with me over his casket. The second dream or nightmare rather, I was in what seemed like a childrens playground in the beach sand (that was wierd) and i wa showing his bestfriend what the playground looked like. Then he disappeared and i saw my husband go into a part of the playground with our son and then I was told he died in the playground. I always wake up crying and sweating. What could this mean?
