Hi and welcome!

Hallways could represent a path that you are going down and a metaphor for your life's path.

You say you are walking down a hall (path) that narrows and is surrounded by panes of glass. The word pane could be a substitute for pain and glass sometimes represents fragile emotions. The feeling of being on a spaceship at the end of this hallway path could represent either feelings of being detached emotionally, or feeling lofty as in searching for higher spiritual goals.

Your boyfriend says he loves you and you respond "Oh, really?" without much emotion, so I'm thinking the former interpretation of the spaceship could mean this.

At the end, you follow the crowd and end up at what you describe as an amusement ride. Do you suppose you would be happier in the meantimes spending more time with friends and hanging out than you would in a commitment?
