Phone numbers?!

Phone numbers?! , why am i dreaming of phone numbers!? , today i entered a lucid dream instantly without reality checks and i keep receiving calls in that lucid from the same number! Actually, of course you can't remember it well, but im a creative guy so i created my own language numbers alone, so nobody can understand the language only me , so when i saw the number in the lucid dream i used my own language as drawing it jn my mind, i still remember the number but i didn't use my language on the last 3 numbers as i was just confused, it was ((00973)) 17388***, My real question is, Why do we receive numbers in our dreams sometime?! That number was all over the place i was dreaming in and he was also calling me!

Any answers?!
