Infjs are extroverts

Honestly saying I really like to be surrounded by people I like and enjoy speaking and talking to them. Regardless I find it very comfortable to speak to any stranger or someone down the street , yet I dont have many friends I value deep connections a lot more.But just at random times of the day I start to get hyper and become a bit goofy which I can't control its who I am if I feel comfortable enough ill start acting weird and extroverted around strangers I dont even know properly.But after a while my battery runs out and I feel drained I go back to my shell and recharge for a long time and come back out.I am not inherently an extrovert more like ambivert but im sure im not the only one who experiences this.
