A storm passed by my place last night. Thunder and the roaring sound of rain startled me from my sleep and I looked through (or "out") the window. The hazy, dark shadow of the old jackfruit tree swayed tremendously and (the moonlight? or the streetlight?) gleamed on the wardrobe in my room, making bright and dark streaks. Raindrops were blown into my room, so I had to close the window. After that, I curled up motionlessly under my blanket to listen to the mixture of sounds. The wind swung the window against the window bars and made rattles as if somebody was ("were") knocking on the door. Fear came into my mind, but an excitement also came after. I kept as silent as possible with light and deep breaths and kept my blanket pulled right up to my neck, as if I were afraid of being found by someone. I felt like I was a kid who was hiding in her room and listen to an argument of the sky father and the earth mother and the rumbles between them. I don't know when I fell asleep after that. When I woke up again this morning, the storm (had) stopped as if it had never come. The old jackfruit stood there placidly and the birds chattered happily outside the window. ~~~~~~ Thunder is a mass noun -- see we don't say "a thunder" or "thunders". We do say "thunder", "the thunder", "a clap of thunder", "peals of thunder", etc. Lights or bright objects can gleam, but I don't think dark things or shadows gleam. "Since then" is used when something started in the past and continues in the present. Common verb tenses used are the present perfect (example: "since then I have walked") or the present perfect continuous ("since then I have been walking"). To talk about something that happened in the past (a completed action or one of a series of events). "After that" is used to talk about things that started and ended in the past. ("After that, I walked to school.")
