Dreaming of time travel is representative of our journey through life. If you traveled back into the past, you need to heal old wounds or get yourself together before you can achieve what you want in your current life. If you dreamed of traveling into the future, your dream could be an escape from daily life or a need for adventure and new stimulations.
If you are constantly having dreams about time traveling, take a closer look at the current situations in your life. Are things going well, or are they more difficult than you would like them to be? Are your dreams a form of escapism and entertainment or are they reassuring you that life is an adventure and to keep moving forward?
