Dreaming of a deceased waking up on his bed

Assalam alaikom respectful mufti,
I had a dream of a deceased on his bed..who suddenly woke up….then people said leave him with his wife now..who was a good looking girl…i was saying al Shahada all the time while i was looking at him that when i woke up i was saying ashahadu ana la elah ela Allah…
what does that mean?
thank you
