In the Netflix short film "Beyond the Aquila rift" (spoiler ahead), we see a spaceship and her crew trapped in a spiders web. The spider plays mind games with them, feeding them simulations involving having sex with people they're attracted to and what not.
It's an open-ended film, but my interpretation is that the spider trapped the ship in her web and eventually wants to incorporate the humans into a hive mind she's running (more on this here). For this, she might take the form of someone they're attracted to in simulations she feeds them and repeatedly tries to convince them to "stay with her here". Anytime they start catching on to something being off, she resets the simulation, leaving only a faint, dream-like memory of the previous simulations.
She keeps doing this until the person breaks down and just accepts getting incorporated into the hive.
Now my question - how might such a species of highly intelligent arachnids come about?
Some options I can think of (I think the first is more likely conditional on observing such creatures):
1) The everyday spiders we're aware of one day evolve intelligence and start trapping our inter-stellar ships in this way (presumably staying in stealth mode)?
2) The spider is a completely alien creature not from Earth, happening to share characteristics and strategies with Earth bound arachnids).
This part is tangential to the main question.
Also (and this is a question about hive minds in general), what might life be like as a human mind that has submitted to her hive? Would a mind (say) interested in engineering be able to continue working on engineering problems?
