In many fanfics, people write that Spock doesn’t need as much sleep as Humans, implying that Vulcans don’t. I myself have written that But I think that I was merely echoing other writers without doing my own research. Bad me

Does anyone know where this is from? Did the fandom make it up? Did Spock actually ever say it in an episode and I just don’t remember? Is it from a licensed Star Trek novel?

Last night I watched a first season TOS episode, the Archons one, and Spock is clearly sleeping while Kirk keeps watch. So indeed Spock DOES sleep and there is no mention of him not needing sleep but maybe he does say it at some point and I can’t recall?

Anyone? Please educate me. It’s been eons since I’ve watched every single episode of TOS but I definitely don’t remember it from the TOS movies.
