Don't look too hard for meaning in this poem. I do not think there is much there. Some poets or songwriters try to communicate a larger meaning that has value to others. They have something to say. Others don't have so much to say, and communicate mostly their subjective feelings and impressions, which have meaning to them but not a lot of meaning to anyone else. The value of their songs are mostly from the music, not the lyrics. This poem is of the second type.
