If you had a dream in which you saw the Prophet (peace be upon him) as he has been described in the authentic sources, then that is a true vision; it is a glad tiding. And it behooves you to thank Allah for this blessing and resolve to be earnest in emulating the beautiful examples of the Messenger of mercy and send benedictions on him as often as you can.

 

Having said this, let me rush to add: A dream of the Prophet (peace be upon him) can be considered as true only if it perfectly fits the description of the Prophet (peace be upon him) as transmitted through the reliable sources.

 

In order to judge for yourself, you may do well to study the following write up by an eminent scholar, namely Shaikh Hamza Yusuf on this. You can access it here.
