Did it move around a bit? Feel really tingly but also pleasant?

That is just energy, most likely one of your angels or a deceased relative touched you or stroked your hair.

That is what it feels like.

Being that you are raising your vibration and becoming use to an increase in energy this will happen more and more often.

Don't be creeped out by out. They are around us all the time and would like NOTHING more than to be 'noticed'.

They love you.

If it scares you they will stay away for the same reason stated above.
