I've been seeing the number 11 is there a good explaination?

Ever since 2011 came i have been seeing the number 11! and i know its not because someone told me about them seeing the same number or repeating number patter and my mind focusing on it because no ever told me anything like that. I have already googled about it and so many ideas about it came up some im having a hard time to believe and some that just dont make sense.
