What does it mean when you have a dream of your ex boyfriend ?

Ok well me and my boyfriend broke up likke a month ago . So ever since i have been really fustrated and sad about the break up . I really liked him . And well the break up really hurt me . Soo last night i had a dream of my ex . Soo well in my dream i went up to my ex and asked him "how come you havent said hi" and he said "well he said becuz your getting kinda annoying" and i said "ok i know i have been getting annoying ok so iam sorry" and then i started crying and then i asked him " look i just wanna clear things up ,is it true that you broke up with me becuz you thought i was embaraced of you" and then he said "yes" and then i told him " look i was never embaraced of you i was just shy, cuz i mean your my first and i had no expierance before" and then i began crying agian and then he leaned closer to hug me and then we hugged for a long time and then we kissed . And thats the end of my dreaam. But the wiierd thing is is that while i was hugging him i really felt like if i was hugging him in person like not in a dream. Oh and its kinda wierd too cuz iam barely in middle school. Oh and well i was thinking about going up to my ex andd talk to clear things up but i wasnt sure if it will work or something before i had the dream. And well i think their is a chance that i could get him bak . Sooo what does this dream mean? Oh and this dream isnt the first their 2 dreams i had of him. Oh and if this helps i really did care for him and i was starting to love him and evendo we only lasted 1 month and a week. And well sometimes when i see him i get all sad and like a little depressed. Ad he always looks at me . And to admit i miss him sooo much .
