communication with the dead?!

Salam.

Some of my relatives had told us that their dead relatives have communicated with them in their dreams . Some of their stories were very convincing .

Then my aunt asked me a few weeks ago, if I have read anything about the dead being able to communicate through dreams . I said no. Later , verse 39:40 came to my mind , :

The Quran 39/40: God takes the souls when they die and during their sleep. He then keeps those that have been overtaken by death, and He sends the others until a predetermined time. In that are signs for a people who think.

Both the nafs/soul of the dead and the sleeping are at the same place with God . Is it possible that they can communicate with each other ? Maybe.
