should I feel happy or scared?

Date: 9/18/2016

I was standing inside a concrete chapel with an open ceiling, I noticed angels flying high above us. I tried to tell the others what I see, but they don't see them like I do. one angel taught me to fly and guided me as we go higher. i reached beyond the skies. in that place I saw teenagers singing with a ukulele and I sang with them. later, I walked by a wall filled with graffiti( I didn't read what's written) behind the wall is a beach with white houses on the opposite island. I walked onto the water and (some crabs I guess or shells) my foot was hurt and I buried to a floating shanty and I ended up crying (I think I was happy and sad)
