Not sure if this the right forum to post. I have noticed and am puzzled by this phenomena for a while, several years. I asked several sources but no one was able to explain to me what is the nature of it. When I meditate, usually at night and about an hour before bed, I would hear random clicking or tapping sounds in front of me. There is a computer desk in front me. When I stopped meditating, the sound would be gone. When I meditate in the morning, after waking up, I don't hear this tapping sound. I am pretty sure the sound is caused by my meditation or my mind but not sure why or how. Or what does it really mean....
Thanks.
