I used to have hallucinations at night, visual and tactile mostly. It was terrifying. Had them every night for months. I got through it without sleeping pills. One of the things that worked for me was to talk about it with whomever would listen and was supportive: a few close friends and a counsellor (was still on a waitlist for a psychiatrist at the time). Eventually it faded on its own to some new horror (heh) but I wouldn't advise taking matters into your own hands regarding medicating (I don't see you suggesting that; I'm assuming you'd need a prescription to get sleeping meds anyway? Not sure how it is where you live...). Also, I agree that it would only be masking the problem. My two cents is to find a way to deal with the hallucinations (some kind of counselling/therapy/something else) with meds as a last resort, if the hallucinations are being caused by an imbalance and not stress from something else. Hope you find what works for you. I wish you peace and safety in the meantime.
