Could be normal, but I would be concerned enough to talk to a pediatrician about it. A video is a great idea, since symptoms can be hard to describe and may not show up at the doctor's office.
Your son may have something as common as sensory integration problems (either over- or under-stimulated by sound, lights, textures or other physical senses) or he could have a brain or nervous system abnormality. Finding out whether there's a problem and getting appropriate treatment early can make a huge difference in a child's development.
One other possibility that may be worth investigating is whether your son has developed a sensitivity to one or more common household chemicals, or common additives like colors and preservatives in foods. Sensitivities/allergies can make children physically or mentally uncomfortable and hard to please, always at odds with their own bodies.
I have severe chemical sensitivities, and get both physical and emotional symptoms to exposures to perfumed toiletries, home cleaning products, fabric softeners and air "fresheners." (Many of these are just downright toxic.) In group testing situations, I have watched children go from contentedly coloring to bouncing off walls, screaming, crying, or being impossibly stubborn just minutes after having drops of some dilute solution squirted under their tongues.
It would be worth checking out. You can try sealing all suspicious products in plastic bags and using free and clear detergent, baking soda or vinegar for most cleaning for the next 2-3 weeks, and watch for any improvements. If reintroducing the products back into the home then results in worse behavior, you'll have a possible solution to work on.
I know this sounds like a lot of change, but it's really not that hard to try. Most of the household miracle products and toiletries commonly used are really not needed, and they are expensive, they are often toxic, and honestly, they don't clean better than a few simple, cheap ingredients. We believe we need them because the advertising is so compelling.
But I've used very little for cleaning in my home besides baking soda, white vinegar, borax, hydrogen peroxide, and scent-free detergent for over 20 years. My house always smells clean and pleasant – and visitors often remark that the atmosphere is "calming." My pet theory is that their bodies are noticing the lack of toxins in the air.
