Can bad dreams affect your personality after you wake up?

Having a nightmare: can impact your mood and your behavior after waking up but should not cause a significant personality change. Take care.

Yes: if you allow them too....Dreams are symbolic language and often tell us some very interesting things...write them down and look up the symbols..then they are less scarey...like death dreams mean there is change coming...not death. Different parts of a house mean different parts of your psyche..dreams are meant to help not harm...
