Ok..I hope I am puting this in the right spot.On March 15 this yr. my Uncle passed away.Then about 3 weeks later I was sitting in my living room watching Tv and a bird ( a robin if I remember right) came and fluttered around the window for a minute then it landed right on the screen and was sitting there looking at me.It left for a minute then came back and fluttered again and then left.About 2 nights or so later I had a dream of a dog howling.My mom always said that was a sign of death.Well guess what..On May 22 my Grandma died then on May 31st my first love died.I am a little freaked.What do you think?

I think that if you want to see something in a series of unrelated events, you will. However, each event is a prefectly natural one, and happens every day somewhere.
Uncles are are almost always older than their nieces, and are far more likely to die before them. The older you are, the more likely your uncle is to die.
Birds are curious, and often land near windows. Yours may have seen what looked like a worm on TV.
Since the information about dogs howling having a certain meaning was already in your mind, it doesn't surprise me that you dreamt about it, especially after the death of someone close to you. You already made a connection before the dream. I told you in another post about this that the mind latches onto memories, and replays them. This is what a dream is, thoughts that already existed in one's mind, often with a new "script."
Grandparents are always older than their grandchildren and usually die while the grandchild is alive. The older you are, the more likely a grandparent is to die.
My guess is that almost exactly 50% of everyone who had a first love will die before their first love. I am certain that all first loves will die before or after their first love.

The only events you describe that may be related are the deaths of your uncle and your grandmother. If the uncle was the grandmother's son, there is no doubt that his death affected her. That may have contributed to her overall health. Other than that, what you described is a series of perfectly natural events, most of which were likely to happen at one time or nother. Nothing supernatural happened.
