First it seems that your uncle maybe currently ill and as we all no sometimes people appear well but inside they feel the sickness overcoming them. You can take this dream in a number of ways; if your uncle does not appear ill he needs to see a doctor to check out his well being;2 If he is ill you have been given a heads up and you should make sure people treat him with well;3 play the numbers that represent hospital death and uncle.
Oh yeah regarding one and two try to search back in your dream to see if there was a remedy. Why becasue one of my friends dreamed that her kids were all drowned in a car crash and she was crying and burning up my cell that day. she was the only survivor. Now once she fully explained the dream to me I could understand that it was a warning to come but careful attention needed to be adhered to the events that lead up to the crash and was there anyway they could have escaped. of course there was and alsmot always is unless the person is really dear to you and you need to come to terms with the death before hand. Oh yeah she could have escape the whole ordeal by backing out of the area were the accident was and she then would only hear about the accident not be in it.
Goodluck
