The second thing, and the problem with telepathy at large in fiction, is that how it actually feels is unknown to us. We have no idea how that would effect anyone psychologically or physiologically because telepathy doesn't exist. There's no way to gauge this, or the damage it could do.
However, if you know someone is in your mind, or has been in your mind, against your will, and you can do nothing to prevent them from not only looking at your deepest darkest bits but also not being able to stop them from putting whatever they might like to in your head? Yes, I could see the term as entirely appropriate and potentially even more traumatic than sexual rape. It'd leave a victim with not only the fear of another predatory telepath doing it to them again, but also they'd have to wonder exactly how much of their memory, habit, and personality are actually theirs and how much may have been put in by the violator telepath.
Spidey in the first scene had no idea that a telepath had been in there. What else did they do while they were in there? Change his favorite ice cream flavor? Make him suddenly forget the unfortunate Amazing Bag-Man incident? Made him forget a highschool crush, or how he beat Hydro-Man the past 23 times, or the smell of baking bread? How about make him salivate every time he hears the word "dendrochronologist" and strip whenever he hears the word "defenestrate". I mean that telepath could literally have done anything to him and he would have been entirely helpless to prevent it, and what more, he may never even know it happened. I could see that as much much more terrifying. I think that's a violation of the very core of one's being.
Mind you, mainstream comics are piss poor at addressing how characters deal with this sort of thing psychologically, so it's almost a moot point. Personally, I tend to use the phrase for the more extreme examples of this. ("You'll vomit uncontrollably for 48 hours when you hear the word parsley" etc).
