What has your experience been with hallucinations or sleep-related hallucinations while taking Concerta?

I have ADHD, hypersomnia, and I’m a complete night owl.
Without Concerta, I can’t stay awake in the morning, afternoon, or even at night. I’m prescribed 72mg and take it every day. If I take less than 72mg, I’m technically awake, but I’m still really drowsy and keep nodding off.
So overall, I feel like 72mg is the right dose for me.
The only issue is that I sometimes have mild hallucinations, but they don’t happen while I’m fully awake. They only happen when I’m falling asleep, waking up, or really drowsy.
Has anyone else experienced this on Concerta?
