I can blow bubbles out of my eyes....it freaks me out. Whenever I am sick or I sneeze to hard my eyes bubble and gurgle. I do not, and would not do it intentionally. I have my pressure at 14 and when my lower and upper eye lids started swelling I thought it was that....but then I missed a night of CPAP.....and my eyes were still swollen the next morning. I am going to see an eye doctor in a few weeks. I am sure it is possible that the air could come up out of the tear ducts. I would see an eye doctor though to rule out anything else....and even if it is CPAP pressure related perhaps they can give you some advice on how to prevent it.
