i just had a dream the other night that i was talking to my grandmother(whom is still living)but she was an owl. she asked me a question and when i answered her she became angry and turned into her humanself, when i asked what was wrong she said something about i had just confirmed the gossip, then i just woke up suddenly. could that mean something???

Maybe you just need to go to sleep earlier so that the night owl does not appear as granny, giving you the guilt trip for not taking better care of your health and reputation. I am speculating about your brief dream conversation, you realize.

It could mean you should watch what you eat just before going to bed. Or, there could be a meaning in there that you would recognize if you probe it deeper. I would recommend getting a dream dictionary and looking up the pieces of your dream yourself, rather than relying on someone else's translation -since no one else was there for your dream but you.
But remember, sometimes a pickle is just a pickle and a dream is just a dream.
