Dreaming of Nabi SAW;an old man

Assaalmu alaikum,I once dreamed of the prophet saw. I did not see his face , only from behind and there was so much of light in front of him that i could only see his figure.He came to my house and as I entered he was leaving,everything that he touched had diamond like stone that were left behind,through out the dream I was running to catch up to him but i never did and i never saw him.What does this mean?
My second dream was that we were having a katham at home and there was an old man dressed in very old clothes but was still so clean and white,he had a white beard and a turban,he had a walking stick in his hand that was unlike any other i’ve seen.All he said to me was’I am not going anywhere, I will be here till the end” Please can you tell me what these dreams mean.

Shukran
