People often report of being abducted by aliens. Yet, the most striking feature of this event is the idea of missing time. Many times people will say how they were taken aboard an alien ship which seemed to only last a few minutes. When they awake sometime later, they are feel groggy and sometimes many hours or even days have passed by. What exactly happened?
It could be possible that these extraterrestrial beings are truly-advanced way beyond anything we humans have ever created. The aliens are able to bend the rules of time and space for their own purposes. So when we awake from the ordeal, to them it took only minutes yet, but for us it took much longer. Possibly, these beings are not of this universe. They could be from another dimension where the physical rules of life don’t apply to their being.
