The pig seen in dream is interpreted as a person of grandeur in whose nature and religion there is baseness, and if one sees it in the dream then it is interpreted with haram wealth. In the light of this detail the meaning of your dream is that you are right in choosing your marriage proposal on the basis of religion. And those who want to choose the proposal on the basis of wealth and worldly possession it is not right. It is a good step to disapprove their act and oppose it. It is mentioned in hadith that the preferred basis of nikah are four: (1) Beauty. (2) Wealth. (3) Power and designation. (4) Religiousness. Then the holy Prophet Muhammad (صلى الله عليه وسلم) said that you should make the religiousness first priority. (Bukhari and Muslim, Mishkah 267)
Also it is sunnah to do istikhara before choosing the proposal. Its method is mentioned in Bahishti Zewar.
