Hi Stef,
I was told by my neurosurgeon that anything a person dreams about is really something that they are thinking about or in relation to something that happened that day or something they saw on tv. My Dr. told me that it's so deep in our subconscious that we don't even realize we're thinking about it and then when we go to sleep the brain is the most active and leads all these thoughts into dreams.
Just like you I have cp and sp sz. It sounds like your sz. are caused by audio and visual matters where you might be sensitive to certain sounds and maybe colors which trigger the sz. Here's wishing you well and May God Bless You!

Sue
