Does anyone know what this dream means? ?

for the past couple of night ive been dreaming about a guy friend of mine one of my closest guy friends, he recently left to the army less than a month ago. the other night i dreamt he came back but he was taller and darker alittle different but not so much. Of course im happy he was my friend and he came back, but then the next night i had another dream about the same guy that he came back and i could have swore he was even taller! the second dream took place in a different location then the first one but i dont understand, i usually dont have dreams with people that i know, the dreams where just alittle weird to me so does anyone know if the this means anything? thank you :)
