It is narrated from Sayyiduna Ibn Amr (may Allah be pleased with him) that once I asked the Prophet Muhammad (peace and blessings be upon him), "O Messenger of Allah! Do you feel the coming of revelation?" The Prophet Muhammad (peace and blessings be upon him) replied: "Yes! I feel the sound of bells, and at that time I become silent, and every time revelation is sent down upon me, I feel as if my soul is about to depart."
