OneNapPod sounds just ike my useful idiot at that age.... Runs around the house at breakneck speed, battering everything he encounters in his path? Does he jump, bite, bark? Spins around and chases his own tail? Does he have madness in his eyes, tongue out, and it's hard to stop him? In our case, phases of doggy zoomies occurred practically every day until he was about 10 months old, so in the evenings I felt like calling an exorcist. He even bit into walls, and our skirting boards are shredded in one or two places.
After the first three months of our life together with Bert, I was able to tell practically every evening that the hour of madness was approaching. You will learn to spot it. The moment when, from a state of relative rest, Bert was turning into a monstrous creature that no force could stop. I tested various techniques for discharging this explosion of energy and, as is to be expected when working with an temperamental puppy, what worked one day, did not necessarily work the next.
As a consolation to you and all those who are struggling with this at the moment - it passes. At first, the rage phase will last shorter, and you will find it much easier to point Pod to activities that help him calm down. Biting and chewing helps to reduce tension - may be why he is so focused on soft furnishings, are his teeth all out at 8 months? He might prefer something soft if he's still teething, it itches and makes them even more frantic. You can ask your vet to have a look at his teeth.
All it takes at the end is time. ZoomiePod needs to mature to this stage and it is the role of the human to understand that every age has its own rights and that we cannot demand from the dog something that we have not taught it before. So just stay patient and just... Breathe. Deeply. A lot. Wine helps. Vodka helps. Cuddling the tired dog helps best.
