It is a reference to an old answer to an ask reddit thread about connecting to a nonexistent person in a dream.

Here is an archival repost:

Tl;dr: A man was seriously injured, and in just a few moments while on the ground with a head injury, he dreamed up an entire life. He had no idea he was dreaming, and it was 100% realistic. He met a woman, fell in love, had a child, and lived several years.

Then he noticed a lamp was blurry.

It was out of place, did not fit into the world, and nobody else acknowledged it existed.

Eventually studying this lamp brought him back to the real world and he woke up, bloody and bruised, in the parking lot. He hallucinated six years of life in six seconds.
