What about if you've been through some traumatic experiences and every now and then you have a nightmare were during the nightmare you start hitting the person next to you..Also what about the dreams that are end up like you just starred in A disatrous action thriller film and you wake up and thank god it was only a dream not a movie?  I gave up trying to interpret my dreams I barely even dream but when I do it's very intense I wake up with severey anxiety!
