I am definitely open to the possibility. After my brother died, I was standing in a Sam's - near the checkouts. The store was not busy and there was no one standing near me. I felt a cool breeze on my face and a strong whiff of my brother's cologne (Devon). I turned around to see if someone walked by and there was no one. My husband "poo-poo'd" this. Then, a few months later he was walking through the living room and stopped short and said "do you smell that?" no, what? He said "I smell Barry's cologne". I didn't. This has happened to him a few more times over the years. So I think we are experiencing a connection to my brother. This gives me comfort.
