My auras / simple partials are usually dream like visions and I usually start spacing out while in the dream. Before my surgery it was just a dream then after the surgery it started with a noice then noise followed by vision now its different dreams.Simple partials usually feature sensory disturbances or distortions -- migraines, illusions, hallucinations, feelings of dread/nausea, deja vu, jamais vu, etc. Basically, weird feelings.
My neurologist did once describe it like sleepwalking, especially my night seizures and my neuropsych described it like being in auto pilot mode where you continue doing things while in seizure.In complex partials the person has impaired awareness. There can be automatic behaviors like Sue describes -- lip-smacking, wandering round, staring, picking at clothes, saying and doing things without remembering. It's a bit like sleepwalking.
I can't get used to the new terminology as before my surgery they were always simple / complex then when they returned they're focal.Officially, simple partials are now called "focal onset aware seizures" and complex partials are called "focal impaired awareness seizures", but many people (including my neuro) use the older terms. "Focal" is basically the same as "partial" -- the seizure starts in specific focal points in the brain. Whereas in a tonic-clonic or an absence seizure, the whole brain is involved.
