Romeo and Juliet Act 4-5

In Acts 4 through 5 the supernatural aspects of the play definitely become very apparent. Dreams are talked about a lot more and ghosts are seen such as when Juliet sees Tybalt's ghost before she drinks her potion to fall asleep. However, in act 1 when we see Romeo's dream is brushed off is no longer now that we are coming to the end of the play. In act 5 Romeo tells us about his dream and what it seems to mean to him. It also foreshadows things to come.
 If I may trust the flattering truth of sleep,

My dreams presage some joyful news at hand.

My bosom’s lord sits lightly in his throne,

And all this day an unaccustomed spirit

Lifts me above the ground with cheerful thoughts.

I dreamt my lady came and found me dead—

Strange dream, that gives a dead man leave to think—

And breathed such life with kisses in my lips

That I revived and was an emperor.

Ah me! How sweet is love itself possessed

When but love’s shadows are so rich in joy!

He has predicted that Juliet will find him dead but her kisses will not bring him back to life. He should've heeded the warnings of his dreams in both act 1 and act 5. This makes me wonder why the supernatural is sometimes ignored and brushed off. Had Romeo listened to his dreams then him and Juliet might have ended up together and been happy. But we will never know because the supernatural went unnoticed.
