When you dream about an alien, it could symbolise an undiscovered, neglected or unfamiliar part for yourself that you need to explore.
Dreams of aliens can also be an indication of outlandish ideas and a wild imagination- could you harness these talents and invest them in something worthwhile? Something creative perhaps- like art or writing?
If you were being invaded by aliens in your dream then you might fear losing your home or your family. Is there anything you can do to stop this from happening or to put these fears to bed?
You may be feeling agitated that your personal space is being encroached upon by someone. Is it time to tell them that you feel uncomfortable by their invasion?
Alien abduction could be due to an inner desire you have to escape from a current situation or your life in general. Perhaps you are tired of the routine of your normal life and want something different- a new job, a new relationship, a new hobby, a new circle of friends or a new location.
If you were having sex with an alien, you might crave something new and exciting in the physical side to your world.
Aliens in a dream can also indicate feelings of adapting or adjusting to new surroundings. Have you just started a new job? Moved to a new area? Begun a new relationship? If so then you may just need to give yourself some more time to settle in.
You may be feeling aliened or disconnected from those around you right now. Is there any way you can reconnect once more?
Another interpretation is that you are struggling to communicate with someone in your waking hours- it feels like they speak a different language. It could simply take time to create an understanding between you both.
If you were talking to a friendly alien in your dream, this could foretell that you will meet someone in your waking hours who will show you new things and be a breath of fresh air in your life.
Finally, you might be experiencing things that are strange or not normal to you right now- feelings for instance and you are finding them hard to explain to others.
