Mind as radio?

I was sitting trying to meditate, trying to focus inward, when I heard someone softly calling me by my name. I recognized the voice and thought she, my friend, was calling me. So I opened my eyes and since I had been deeply concentrating, it took me a few seconds to adjust my eyes to the light and to the environment around me. It was chaotic .. there were thousands of people gathered in one hall, and I had been sitting in an obscure corner by myself. I looked around for her, but could not see her anywhere. Weird, I thought .. I was pretty sure I heard her voice distinctly calling me .. maybe it was just an illusion. I closed my eyes and started meditating again.

About 3 minutes later, I was aroused by somone tapping me on my shoulder. It was my friend's husband. He told me that they had just arrived and he had been looking for me in order to give me something. I asked him how long ago had he and his wife arrived. He replied "less than 5 minutes ago. Why?"

What could I tell him? That around the time that he and his wife had entered the room, I had heard her voice calling me? That this was not a stand-alone incident and I had had experienced this a few times earlier as well with other people? That when people thought intensely of me, I would be able to perceive their call in some way?

Instead, I just shrugged and smiled. Ignoring his question, I turned the conversation to different matters.

Sometimes I think the human mind is both a radio transmitter and receiver. And depending upon the clarity and tranquility of the mind, the mind can pick up thought waves, especially if the transmitted thought waves have a large amplitude (intense thought). Scientists will shudder at my hypothesis, and while I dont have scientific proof to validate this, I have had enough empirical evidence to support this phenomenon. Sigh. How little do humans know!!
