I remember when I was a kid , my kindergarten decided to play a movie for kids in the afternoon , I think it was Rapunzel.

There is a space after commas and full stops, but not before

At that time I was 5 years old , everything was magical and whimsical back then. , I recall when our teacher had gathered us together before the movie started ; it was getting dark and we were thrilled to see the movie even though we didn't understand the plot ,. I also remember that when there was a kissing scene the man operatplaying the movie tried to hide it by using his hand to block our view . We started to giggle because we knew what was happening, a. As we were watching my dad came to pick me up at around 6:00pm , e. Everything felt beautiful and magical, from the yellow lights in my kindergarten to the crisp air outside .

Full stops end sentences :)

I still reminisce about that night , maybe my personal connection with the night time is due to that memory or perhaps my love for movies and yellow lights is.

By having "or my love of movies and yellow lights" after "due to that memory" it sounds like you're listing it as a cause, and not a result, which is why I restructured this sentence a little.
