This dream reflects that you have a kind heart. Buddhists emphasize that all beings are equal and can become Buddhists. As long as your character cultivation can be detached to a certain level, it is what Buddhists call "nirvana", that is, the spirit is sublimated to another level (I don't know what nirvana is), which is called "becoming a Buddha".
The above is just my superficial understanding, for reference only.
Have a nice day!
