In my respone I'm dealing with coming out of the imaginative journey back to reality, and for Lucy.. I say that the persona DOESN'T escape the imaginative world but rather chooses to stay in it, aided by the apparent use of LSD.. and you can support that by the 'climb in the back with your head in the clouds' which is a double-entendre because it refers to losing yourself in the imagined landscape and being under the influence of LSD.
Are you doing Journey to the Interior as a related text? It works really well with the song for comparing/contrasting
