I have recently been able to get my hands on an antique book titled:
THE NATIONAL DREAM BOOK
By Madame Camille Le Normand
Whenever I have a quite distinct dream now I try and refer to it and see if it bears any significance.
There is a specific entry for the Wolf and It is as follows:
The wolf signifies an avaricious mam, cruel and crafty; hence to dream of having overcome a wolf, predicts a triumph over a man possesing the
characteristic of that animal; but if bitten by the wolf, it is a sign of exactly the contary nature.
Now dreams are specific only to YOU, and only you would know the real meaning. If I were to hazard a guess though as I see dreams as a kind of glimpse
into the very near future, that your Brothers time in this World was over and that the dream was to be a comfort to you, the pain only being there to
make sure you remembered it.
My sympathies, take care. Hope this helped a little.
