Bebo's Birthday and Visits from his Spirit

My mother's brother, nicknamed Bebo, died of spinal meningitis in Cuba many years ago when he was just ten years old.  His birthday was August 1st and sometimes on this date, odd things happen to members of my family.  Several of us are convinced that these odd occurences are Bebo's spirit contacting us. 

Here's a telling of two of Bebo's contacts with us:

Many years ago, on an evening of the 1st of August, the day of Bebo's birthday, my Mom and brother Charlie were sitting in the family room of our home in Hialeah.  They saw what they described as a perfectly round "moon" in an orange-ish color floating in front of one of the walls of our family room.  I now know that they saw an orb, but back then, I didn't know the word "orb."  My mother and brother were stunned by the fact that this round object, very solid in its makeup, was not reflected on the wall, but rather, was floating a few inches in front of the wall.  It remained visible for a short time and then slowly dissipated.

My uncle, Tio Nene, and my aunt, Conchita, experienced something powerful and frightening on an August 1st many years ago, in their Indianapolis home.  Everyone in the house was asleep--my aunt and uncle, my aunt's mother, Oli, and my cousins, Bibi and Chino--when they heard very loud noises coming from the first floor of the house.  The noises sounded like burglars in the house so my uncle immediately contacted their neighborhood security.  My uncle opened his bedroom door and yelled to the others in the house to lock their doors and stay in their rooms, and that he'd called security.  As my aunt waited for security to arrive, she remembered that there was quite a bit of cash in the kitchen underneath the dining table's centerpiece, and she figured that would be stolen.  The noises--banging and breaking noises--were so loud that my aunt and uncle expected to find their house destroyed.  When security arrived, however, they found that no doors or windows had been broken, or even disturbed, and when they came into the house and the family came downstairs, everything on the first floor was in perfect order.  Nothing had been disturbed, and even the cash on the dining table was just where my aunt had left it.  My aunt said they were very embarrassed in trying to explain what had happened to the security people, however, she took comfort from the fact that the entire family heard the racket, so she knew she didn't imagine it! 

I'm troubled by this experience.  It happened on an August 1st--Bebo's birthday--and that's the date that he generally chooses to "manifest" to his family, but why did he scare my family?  From all accounts, Bebo was a sweet child, so the poltergeist-like activity experienced by my family in Indiana doesn't quite fit the picture of the spirit of a gentle boy, whereas the experience my Mom and brother had, witnessing the orb, is definitely what I'd expect from Bebo.

Any thoughts, anyone?
