What Causes Ear Bleeds At Night Without Trauma?

Good Afternoon, I have been experiencing ear bleeds only at night without any precursor trauma other than potentially acoustic trauma. Additionally, I have had intermittent ringing in my ears rarely. Two days ago, my left ear was bleeding slightly, last night my right ear bled enough to leave some spots on the pillow and leave dried blood throughout my ear canal. Otherwise, I haven t had any hearing degradation or absolute loss, no balance or motor issues. I cannot see any scratches or abrasions within the ear canal, and finally I haven t experienced any headaches. Any ideas what this could be? I appreciate your help.
