My dream

I have had to dreams. my first dream. I am currently living away from home and have been here for a while now but am moving home soon. i have made new friends now and I had a dream that when I got home I couldn't stop crying because i missed my friends here. Just everytime I thought of them.
My second dream was about my dog while I was away he died from eating a diseased rat. And I miss my dog so this was sad. This is really weird what does it mean. HOpe you can help thanks.
