Our dreams drench us in senses, and senses steps us again in dreams.

The line suggests a reciprocal, almost circular relationship between inner life and outer experience. Dreams “drench” us in sensation—vivid images and feelings that can seem as tangible as waking perception—while our waking senses, in turn, “steep” (the likely intended verb) us back into dream, supplying the raw materials that the mind recombines at night. Read this way, Alcott is collapsing the boundary between imagination and perception: consciousness is continuously oscillating between the two, and neither realm is fully independent. The phrasing also implies that what we take as reality is partly dreamlike—filtered, colored, and reconstituted by the mind—while dreams are saturated with the textures of lived experience.
