I've had this problem before. Seems that all of a sudden I was seeing 11:11 just about every time I looked at the clock. I read up on some sites and honestly none of it really hit with me. So I just put it out of my mind and after a while I stopped catching that number.
I don't know about your specific situation, but I know for me I think I was in a place in my life where it seemed like my life just didn't have any meaning anymore. I wasn't working and I didn't have many friends. I think I was just trying to impose some sort of higher meaning from all this.
Who knows, maybe the alien life forms were trying to contact me. But they never did.
I wouldn't stress about it. I hope this helps.
