Sleep is actually a combination of 2 systems, your sleep drive (like hunger) and a biological clock that tells you when to sleep. When both are working well together, you sleep best.

These days, it's far too easy to push bedtime aside with countless distractions, including those from the television, computer, telephone, belated responses to email and text messages.

Your sleep-wake cycle follows a regular pattern (circadian rhythm) and when you sleep "too much" that pattern shifts.

The dream represents a question or message (often related to a limitation, fear or doubt) to the dreamer. It will reach a conclusion once the dreamer understands the message and resolves to make a change.
