A lesson regarding introduction to dreams by our Priestess, Drakkenwitch; "... Technically speaking, a dream is a hullucination. A dream is also a fantasy journey in our sleep that either reduces our stress or tries to live out our greatest fears in the safety of our sleep. When we sleep, we get rest and relief from our waking days. In this sense, dreams are a way of relaxing and letting our minds drift away to distant worlds. In this state we can interact in a non-Physical sense with people, places, and both."
Why dont you try creating a dream diary. Keep it close to your bed and write down your dreams. Good luck to you.
