It looks like you're working on an exercise involving the past simple and past continuous tenses. Here's a possible way to fill in the blanks with appropriate forms of the verbs, while also structuring it into a coherent narrative:
Yesterday, I drove my car to the library and then I went to college. While I was walking along the road, I bumped into an old friend, Alex, who was sitting in a cafe when I arrived. He called me over, and we had a nice chat.
Later, I was cleaning my room when I saw a spider. At that moment, I was whistling a tune because I was feeling quite relaxed.
Last night, at 10 PM, it was really noisy outside because people were having a party.
Feel free to modify any part of it or ask for further assistance regarding past simple vs. past continuous!
