What does it mean when you dream and receive signs of the virgin mary?

A while back I dreamed that my family and I were traveling up on a mountain, which I've gone to it heads to a small pueblo(small town) named "real de catorce" with religious beliefs etc. Then as we travel up on a boulder a bright light started to appear then the image of the virgin mary appeared from the light and moved as if it was floating and slowly floated to the left when we turn to the right side. When we arrive to the top of the mountain we accounterred my aunts house was there instead of the pueblo. I haven't seen my ain't in years. Then today I was using my phone and my phone powered down and when I turned it back on there was a picture of the virgin mary set as my wall paper which I didn't have on my phone. I showed my mom we both didn't know what to think, my mom thinks that it may be sign for something I don't know. I am catholic and the virgin mary is my saint. I really want to know what it means.
