Do spiders dream?


They seem to — they have behaviors suggestive of REM sleep.

I want to know that they’re dreaming about. The investigators in the video above have a clear idea of what a spider nightmare would be like: they wake them up with a speaker that buzzes at the frequency of a wasp’s wingbeat.

So now we know how to terrify a spider, in case you were looking for that kind of information.

    They could be dreaming about how to subvert the World Wide Web because they’re jealous.

    I thought of you when I saw that article in SciAm last night. It doesn’t surprise me that spiders seem to dream, or anything with a brain.

    Then I thought of Pharyngula when I saw the article about more men getting vasectomies since Roe was overturned, wondering when Elon Musk and the GOP Christo-Fascists would start passing laws to restrict access to the procedure.

    Do spiders dream of electric flies?

    Or doing a web search?

    I ‘spose they dream of spidery things, of spinning silk and sucking down food and evading birds and their spider lives.

    This was a remarkable and beatiful clip and study..
