What is The Matrix really about?

Lisa received a motion alert from her porch camera at 5:29 AM. When she reviewed the footage, she noticed something chilling. A boy suddenly appears sitting on her porch holding a plate. One second later, he's gone. What's even stranger is the movement in the bottom right corner may resemble grocery bags that weren't delivered to her house until 8 hours later. She also shared that her son was a twin in utero, and the boy in the footage looked eerily similar to him. Glitch in the matrix? Paranorm
