My 6 yr old daughter asks herself/me deep thought provoking questions?

My daughter lately has been asking, mostly while riding in the car or at home when she has her notebook things like "who am I? I know Im makenna, but who am I inside?" and " I know I used to live before this, what was my name?" She has also been very intuitive.. We live in mpls and the day before the 35w bridge collapse she started drawing out maps of the freeways and saying dont go on 35 go around on 94, ok mom?" and she kept bugging us about it. I didnt even know she knew the names of the freeways. I didnt think about it until it hit me the night of the collapse. When it happened we turned on the news and it took a min for me to realize what it was cuz it was such a far shot of it. You could only see smoke and she said "a bridge fell". We turned it on in the middle of the report w no indication except for the smoke. She knew right away. Other things she has said since then too. She was very upset and preyed about it for weeks after. How should I handle her questions?
