There may be an underlying seizure or metabolic condition. Please see your physician and watch for respiratory difficulty. Are you otherwise healthy? Have there been an recent changes in your weight or diet? More information would be helpful and a virtual consult with Healthtap is available.

Dr Kuitems and another doctor agreed

With this symptomatology partial seizures are a possibility here. I recommend going directly to a neurologist for accurate diagnosis,testing and any appropriate treatment, if needed.

Advise you have these "spells" fully evaluated by your physician. Not clear if these are syncopal or pre-syncopal, and could even consider seizure auras. This could be associated with anemia, hypoglycemia, thyroid, dehydration, medication or drug reactions. Until clarified, would avoid driving, activities at heights, use of power tools, bathing or swimming alone.
