Some dreams reflect great frustrations. For example: missing a train, not being able to read a message, searching for something without finding it, failing to convince somebody . . . Maybe you think that your life is not going the way you want or feel angry at others' stubbornness. It is very important to find out what frustrates you so much in real life in order to deal with issues in a more effective manner. The oneiric superstition says that frustrations mean the opposite: they predict great success in your plans.

Do animals dream?
Research conducted by various scientists show that animals do experience dream while sleeping. They also experience similar sleep stages like human beings - REM and Non-REM. If you have noticed a dog sleep, it might sometimes wag its tail, this indicates some response to its dream. A study was conducted in a cat by removing a part of the brain stem, which will not prevent it from reacting to the dream during REM. It was noted in some cats they were aggressively chasing mice as in reality.
The amount of sleep that a person gets will be associated with his or her lifespan. However, the causes or effects are still vague, as illnesses can also affect a person's sleeping pattern. According to a 2010 study, women under the age of 50 to 79 only get less than five hours of sleep every night, which makes them a subject for death occurrences.
