I am certain there is a difference between "dreams" and (for me) "visits", and probably many other types I'd love to hear of.My reasons are that I have lots of trouble sleeping. But when I am asleep.I'll know I slept.Anyway 1 example is that I lost my 19 year old son to suicide,and often while praying ask that he know howloved and missed by me he is.One nite,WHILE praying,so AWAKE.I felt the lips that were his alone,on my forehead,and a quiet "I love you Mum".a few days later,in alot of pain physically,I felt ONLY his hand, a Mom knows! One pushed hair from my forehead,the other rested on my prayer-folded hands with whisper"it will be alright you need to rest. Many other unconvinced it was the wind type of Heaven sent messages! Kept me going a very long time!
