Meaning of ‘the world beyond’

Meaning of ‘the world beyond’

The passage below is from Fathoms: The World in the Whale Hardcover by Rebecca Giggs.

A series of studies, begun decades ago, showed that the preponderance of people surveyed remembered their dreams as being screen-coloured. Adults who grew up watching black-and-white television tended to report dreaming in monochrome for

the rest of their lives. By the 1960s, after Technicolor, 83 per cent of dreams dreamt by the dreamers surveyed contained at least some colour. Now I wondered if the gentling tones of the environments I scrolled through online were imprinting on my sleeping thoughts; touching-up the nature I slumbered within. A hypnogogic nature cleaned, intensified, brightened. A nature that made the world beyond look, in truth, a little dull.

In the passage above, I want to ask the implicit meaning of ‘the world beyond’.

To me it seems to mean not a dream world but ‘the real world, the awaken world’ since she talks about a hypnogogic nature in her dream in the previous sentence.

Am I right?

Thanks in advance.
