birthmarks and 3-4 am awakenings
Birthmarks are nearly always remnants of a past-life trauma. I've hung out with enough past-life regressionists at whole life expos to have heard plenty of stories of people who re-lived violent deaths and the injuries matched their present-day birthmarks! :)
I'd say the present you translated the knife stab into needles because you're so health conscious right now.
Since I already gave you a reading on 3:11 I'll just add that people tend to wake up around 3-4 am because of the hour it is. I forget what it's called in Ayurvedic terms, but it's a very cleansing, light, airy couple of hours, and for some reason magnetic/psychic messages/leyline vibrations are stronger than usual.
Kryon says this will happen to Lightworkers, waking up at 4am, and they should just enjoy the time and not worry about insomnia.
More ill people die around 4am than any other time.
Monks get up at around 4am to meditate because we have higher concentrations of melatonin/pinoline, so anything we visualize in order to heal is better translated into our physical bodies.
Just some metaphysical ramblings! :)
