Plenty of people open Reels or Tiktok the second they wake up. Mobile means notifications, and of you see one as soon as you turn off the alarm, you're more likely to open the app.
Yikes, that would be a nightmarish way to start my day. I like to wake up and orient myself to the world before I start engaging with it. I often ponder dreams I woke up with to ask myself what they might mean. What you describe sounds like a Black Mirror episode to me where your mind isn't even your own and you never really wake up.
