There could be a repressed memory causing PTSD for you.
However, the way you described it resembled something I struggle with. Perhaps youre interpreting the experience this way because you are just confused by what is happening to you. Thats how it started for me until I learned what was really happening.
Do an extensive search on Panic Attacks and Panic Disorder. Its NOT what you think. Its not anxiety. Its full blown panic. Episodes of nausea, loss/blurred vision, muscle weakness, tingles on the skin, hot/cold flashes, heart palpitations, sweating, paranoid thoughts like youre dying, etc. More often than not, they happen unexpectedly and fast.
