"I've dreamt in my life dreams that have stayed with me ever after, and changed my ideas," reflects the profound impact that dreams can have on a person's thoughts and perceptions. These dreams are so powerful they seem to permeate deeply into the mind, influencing how one views the world and oneself.
As Emily Brontë describes, these dreams are like a transformation that alters the "colour of my mind," akin to wine blending with water. They leave a lasting impression, shaping a person's inner landscape and affecting their consciousness long after waking. This highlights the enduring nature of impactful dreams in our lives.
