Dream

My brother passed away two years ago at the age of 39 in Ramadaan. Quite often I dream with him, last week I dreamed that I asked him to come back that we all miss him, I usually say that on my other dreams also, he replied that he can't come back that the place he is in there is no coming back and that he must stay there forever. So I asked him that the sinners are getting punished there, must be bad, so he said, it's not so bad like you think, and again I I insisted about him coming back, and he said it is not possible, plus he said, prepare yourself, you coming to meet me soon. My question is, is this shaitaan playing with my mind or should I believe my brother? If it is my brother then what is your advice to me. Shukran.
