All throughout the centuries, dreams have found the path to our minds. Topics are wide and varied. There are mysterious messages, warnings of impending danger, future events, even winning lotto numbers. Some people claim they never dream, while others profess to having several dreams in a single night.
Memory is a vital link, since dreams happen late at night during deep phases of sleep.
A frightening dream experience can result in waking up with a jolt. Startling dreams of this sort are likely to be remembered. The calmer, non-threatening episodes are the ones we tend to forget. Unless we wake up there is little chance of recalling the dream the following day. A ringing alarm clock can be an asset because the early morning dreams are easier to remember.
