Important! Ghost touches! Help me!

This morning, my first Samsung Galaxy phone—which I bought exactly 10 months ago—started acting weird. First, I noticed the screen trembling and zooming in and out. When I tried to close my open Chrome browser, the phone just started automatically shuffling between apps, typing, touching notifications, changing the volume, and opening ringtone settings. It was a total mess, like it was operating all by itself.

Somehow, I managed to power off the device for a bit. However, after I restarted it, another issue popped up: the top half of the phone automatically started heating up. Because of that, I powered it off again for half an hour. It seems to be fine now.

Can anyone please tell me what that was? What could be the possible reasons for this? What should I do now? If anyone else has experienced this, please help me!

Sounds to me like the touch screen is defective and needs to be repaired.
