Body problems of the 2015 Honda Accord Hybrid

I was driving to work at approximately 6:45am on Friday, 10/14/2016. I was traveling on at approximately 70 mph on i95 north in light traffic. Weather conditions were ideal. After driving for approximately 15 minutes, I head a deafening and startling explosion; the noise was similar to that of a loud shotgun blast. I swerved to the right - I was lucky traffic was light. I looked around but traffic was proceeding normally. My first thought was of a truck tire exploding but I saw no trucks. I then considered someone may be discharging a weapon. Finally, I heard noise of the wind above my head and pulled off at the closest rest area. Once I stopped shaking, I inspected the roof of the car and saw the shattered glass. I called my husband then my supervisor. Finally, I drove to the dealership and reported the issue. The customer service agent told me they would have to contact Honda to report the event. They initially told me that renting a vehicle would be $33 per day. After the service manager arrived and the customer service rep spoke to him, he authorized a rental at no cost. After several hours, I was assigned a rental vehicle and I drove home. The csa called me and reported that the dealership had found evidence of something striking the front of the car, bouncing onto and shattering the sunroof, then denting the truck of the car. From a dynamic perspective, I do not believe this is possible plus the only noise of which I was aware was from overhead. Also, granted it has been only four days, but I am very skittish about driving. I have lost all confidence.
