Same for me, got 6 endings, I think i got all the dreams and the last one was repeating itself on each restart, but no trigger. I know what happens after because I saw a walkthrough but wanted to experience the game myself. I'm using firefox, there is a 5 in the bedroom too.
It's a nice and cute game, I enjoyed watching and playing it and a perfect match for the theme in all aspect, good job! :p
