Hi @babswood,
How are you feeling today? So sorry to hear that you’re having nightmares, I know this can’t be easy for you. There has been a lot of conversation on sleep issues on the forum, you might find the following thread helpful; Dreams and nightmares - #7 by Chantell75. In terms of your medication, please speak to your GP or Parkinson’s nurse about this as they may need review your dosage. Also, for your own reference, we have info on our website about ho Parkinson’s drugs can affect your sleep, please see it here: Medication, sleep and Parkinson's | Parkinson's UK.
Lastly, you can also give our helpline a call for more support on this.
Best wishes,
Reah
