Making Things Up, by Helen Thomson.

“Our reality is merely a controlled hallucination reined in by our senses.”

If this is so, what happens if we loosen the reins?

You may have seen the basketball/gorilla video which shows us that we can only concentrate on a small portion of our visual field at once, and that our brains fill in the gaps. This article explains that in fact, most of our perception consists of our brains filling in the gaps.

The article proposes that most of our perception is in fact a form of externally guided hallucination. It also contains instructions for how to experience hallucinations at home – safely and legally!

“Far from being flights of fancy, hallucinations reveal the true nature of our reality.”
