Absolutely as well. As a child I would have visitors with messages. As an adult I have encountered several, especially in homes that I show (as a Realtor) as well as the fleeting ones in my gardens when I am working in the dirt. Had a visit from my grandfather that he had passed, told my parents (as it woke me up) and they didn't believe me...until the phone rang 30 seconds later and it was my grandmother relaying the news to my father.
