The death sun

I woke up at 3:00 am (devils hour) I was getting on terraria and a creepy sun popped up for 2 seconds and disappeared I was like watt? I opened terraria there was a title saying matahari mati so I looked it up it was Latin for sun of death. I was already ready to leave but I wanted to play so bad I played. So I went on my terraria files nothing was there accept file worlds so I looked on it one world was called sun of death I was like >-< I'm scaredddddd. Still I went on the world. nothing in my inventory accept a pickaxe called @#^%$^!(#*#& D! |=. I was like is it me or dose

D! |= mean die.......I looked at the sun and it was... Red and black and dripping blood.it killed me in game once I hovered my curser above it I tried to mine with the pickaxe. Killed me in game again.. and I hovered my curser above it again and a black and red dripping moon lord spawned with 1000000000000000 health in all they eyes and killed me. right away tried to go away when I exited terraria I deleted it and reset everything.....
