I Am Reading Several Post That Are Similar To What

I am reading several post that are similar to what I have experienced. Bruising around my eye upon waking, no trauma, coughing, straining, injury, no blood thinners or unusual medication, no reason that I can explain this. My doctor seems to think that I must have done something in my sleep.. I am quite sure I did not and am looking to see if there is possible any other reason for concern.
