What's with me and having weird dreams?

like, i had this dream a few nights ago about me sitting under an oak tree in the middle of some rural country place, and suddenly this really old man starts walking down the street, and he sees me and smiles, and then he looks at me with really wide eyes and gets all frightened, and then starts shouting something in some other language, like greek or latin or something... I dont know.. but then keeps repeating it, i think it was like "Pravuhs de martyres" or something like that. then he ran down the street with his cane and then the ground in front of me opened up and a big ditch or cliff or something appeared, and then something was coming out, but i woke up then, and my mom was shaking my shoulders and saying, "What's the matter?? you were yelling in your sleep!" and im just like, wtf....
