Step-by-step explanation:
The poem begins with the speaker describing a dream they had about an old man who is holding a rose. The rose is described as having "the life of the man" and "the colour of blood." This could represent the connection between life and death, as the rose is both beautiful and fragile, and the man holding it is old and nearing the end of his life.
The speaker then describes another dream in which they are floating on a river and are surrounded by people from different cultures and backgrounds. This could represent the diversity of the world and how we are all connected through our shared humanity.
In the final stanza, the speaker reflects on the fleeting nature of dreams and how they can be both strange and beautiful. The line "I have walked in my sleep, as if all my life were a dream" suggests that the speaker is reflecting on the transience of life itself.
The poem seems to be exploring themes of life, death, diversity, and the nature of dreams. It encourages the reader to reflect on the beauty and fragility of life, and to appreciate the diversity and interconnectedness of humanity.
