I got to wondering how ancient is dreaming, anyway?

Looking around on the internet, I found sites related to nyctinasty - sleeping plants. I was reading this awesome study, "Metabolites involved in plant movement and ‘memory’: nyctinasty of legumes and trap movement in the Venus flytrap" and happened to notice in section 2 the words, "indoleacetic acid".

The reason that caught my eye is because I hardly ever recall my dreams, and a while back I had been taking a couple of tablespoons of vinegar every night before bed as a home remedy for something unrelated to dreaming. As a side effect, I started remembering a few, short, but vivid dreams.

Vinegar contains acetic acid, so when I saw "indoleacetic acid", I wondered if these nyctinastic plants were not just sleeping, but dreaming. Wouldn't that be cool?

Here are a couple of other links about nyctinasty. (does anyone speak Latin? ha ha):
