Yes free will, free choice, of course.
But I can be influenced as well.
If some ghost appeared in front of me and then vanished, then sure I have the choice to do what I will with that information.
But I am however influenced, almost compelled, to now change my thoughts from here on out. Hard to help that.
Did it do me any good? Or was it a detriment? Should it be used as a helper to advance myself, or should I discard it best I can since it might be an attempt to distract me? See what I'm saying? Playing with some of this stuff might burn me.
SI, if it doesn't bother you I doubt it can have any negative effects
