First time on ADHD meds and I’m having extremely weird and vivid dreams

I just got diagnosed with ADHD and they prescribed me Metadate, which I’ve been taking, but they’ve led to some pretty bizarre dreams. Just this morning I had an extremely vivid dream that my boyfriend was cheating on me with Arianna Grande and I was threatening to jump off a roof???!! I’ve never really had these kinda of dreams before and honestly they are kinda stressful. I have some degree of anxiety and waking up anxious or stressed can really exacerbate it. I know this sounds stupid but has anyone found a way to reduce the occurrences of nightmares or shitty dreams while on medication? Thank you.
