"Tortured" is an extreme word. I know a lot of media typically portrays the abduction experience as torture though. It's more of an invasive medical examination that people don't understand performed by beings that are unfamiliar and scary-looking. There's never any clear sign of malevolence or benevolence.
Also, hypnosis has been known to be able to help some people be able to recall documents word-for-word, and the Hill's hypnotist said they were both excellent subjects. Betty was instructed by her hypnotist to draw the star map only if she was able to remember it completely accurately. She did.

And yeah, I'm often quite surprised and appalled that with all the evidence it isn't more widely known either. Most of it can be credited to plausible deniability and the aura of ridicule.

I take hypnosis with a grain of salt myself.

I will believe that you were visited by aliens as much as I believe Dumbledore was killed forever by the Balrog inside the Death Star.

I still think it implausible aliens would seek out the Earth considering the size of space, not impossible, but implausible.

If aliens are as interested in aliens as we are, then I would imagine the moment they find Earth they would try and study it or whatever else they want to do with us.
