If the spider is within reach, what about trying to smack it with a rolled up newspaper (even if it ends up being a hallucination)?

I'm just wondering how your hallucination behaves. Like, what if you try to smack it, will the hallucination be "smart enough" to show a squished buggie? Or will the hallucination behave differently?

And will the spider scurry away when you swat at it? Spiders naturally scurry away when swat at, but maybe a hallucination won't?
