well for one thing you're taking sleeping pills that make you hallucinate these crazy things why? i get prescription and whatnot, but have you tried various herbal remedies? [i'm not saying throw your meds out the window, i'm just curious if anything that doesn't cause hallucinations have helped.]
if it feels different, perhaps it is bringing you to a state where you could be more aware, but since this meditation seems to be designed to make you sleep and a side effect is hallucinations, i would say probably not. but on the other hand, i can think of a few religions/cultures that use hallucinogenic plants to get into a spiritual state. these two instances are different to you than the hallucinations, and they both share a similar feel [smoky quartz] so it could be. perhaps try talking to them, or if you can't in this state, try meditating and asking questions, or you could use a divination tool to communicate with them. anyone can in theory connect with spirits, you just need to strengthen your clairvoyant side.
