That night at my grandmother's house. wc is out of the house. i went out to go to wc. it was about 3 am. my grandmother's backyard is very large and behind the house is a large garden with many trees that have no lights. the instant i came out of the house i immediately saw that object. the top of the trees at the bottom of the yard. i think the diameter was a bus size. it was silver and slightly shiny with white and blue lights. i did not feel scared and curiously went to the middle of the yard, but when i got closer, it moved back. when i was moving, i felt a sense of a warning to my mind. i was afraid and persistent. i looked at it for about a minute, so long, i felt like he was looking at me. then i went back a few steps and then went back and then suddenly disappeared quickly to the top.
