"My aunt comes" for relaxation.

This is a story I made in Writing class. I would like to know whether you understand the word aunt means.

After a whole tiring day, I was almost burned out because I worked at a constrution site under a big sun for one day. When it was break time, I talked sleepily with one of my partners, Jill, because of my fitigued feeling ; as she kept talking vitalitily with waving her hands left and right, my head nodded up and down then I felt sleepy bit by bit. Just as I was sleeping with my muscle releasing, I heard a sound aloud which came from the backyard where no body could stay there at night. With my curiosity, I dressed up my full-cotton jacket and took a large bat hanged on the wall which my brother used it to play baseball. I walked toward the backyard as soundless as possible, then a lightning came over the dark sky and after a few seconds it thundered. As seeing the scene, I was scared to die, but I had to be brave because I did not figure out who made the strange sound. While I was walking on the moist lawn, singing loudly to brace up, then I saw something moving behind of an olive tree which I was often playing see and hide with my my cousins during my childhood,the closer I came to the tree, the cooler I got. With almost zero distance from it, I could clearly see what exactly it was behind of the tree. I opened my eyelids as big as possible, grabbed the bat tightly which already got wet and sticky, and then I saw something white fluttering, "There was a ghost" I thought ,and I screamed out loud. With that, I threw the bat toward the terrific ghost which just stayed at the original spot with no little moving and then I ran away quickly with leaving one of my slippers at that site. The other day, I went and checked that site, I saw my slipper gone and there was some kind of red liquid on the lawn. I was shocked again. Then I woke up and found that it was the time for my aunt to visit with me.
