Premonitions feel like real life and that your actually there. I have had these before and there is a striking difference between dreams and premonitions.
Dreams are more like your can still feel yourself lying in your bed asleep and yet you really aren't aware your asleep.
remember premonitions feel exactly like real LIFE dreams on the other hand don't.
I have had many premonitions and many dreams and I knew which ones were dreams and which ones were premonitions because some premonitions I prevented and some I actually saw happen.
