Question:
What the hell is the matter with me if when i lay on the right side of my head i hear a heartbeat?
Answers:
The internal carotid artery passes very close to the external auditory canal. When you lay your head against the pillow the pulse causes vibrations that are picked up by the tympanic membrane, allowing you to hear your heartbeat.
