Bright Purple Light

My sister has always had difficult pregnancies and she always ends up having miscarriages. So we were all excited when she was able to last 5 months being pregnant. We thought this baby would survive. Unfortunately, her pregnancy became very difficult and she gave birth to her son when she was only six months pregnant. Ten days after he was born, my baby nephew passed away. I never got to meet him.

About three months later I woke up feeling really depressed and I was watching the only video I had of my nephew on my camera. I was upset that I never got to meet him and I wondered if he knew about me, and that I love him. I was in bed crying and I look toward the doorway and I see a bright purple light that is slightly bigger than a baseball float in to the room. The light was purple on the edges and faded into white towards the center of it. The light lasted about three seconds and then faded away.

I had no idea what that light could have been, until one day my eleven year old nephew (my sister's only son and the brother of the one who passed away) told me that he also saw a light the same size as the one I saw, only the one he saw was white. He told me it was his baby brother. My nephew also never got to meet his baby brother.

Could this have been my nephew? If so, why was my light purple and my nephews was white? If any of you have any ideas of what this could have been, please let me know!
