Was this a sign from my brother?

Whenever my brother took his regular nap, I would then walk around the perimeter of our house for exercise. When I passed the window of his bedroom, I would always knock 3 times on the window to let him know that I was outside in case he needed help. When he passed away, I was devastated. I continued to exercise outside and would knock 3 times on his window in memory of happier days. Then one day recently when I knocked 3 times, I heard 3 faint but distinct raps on the window in reply. Some people have told me it was definitely a sign from my beloved brother. Some have said that it was an auditory hallucination. I KNOW it was NOT a hallucination. Is there a possible scientific explanation for those 3 raps? Or is it possible that it really was a sign from my brother? (Actually, I was so stunned that I knocked 3 times again and I heard again those 3 faint but distinct raps. I even did it a third time but there was only silence.)
