A number of events or prevailing conditions can alter the perception of time, so that it may appear to a person that hours have passed in seconds, or minutes seeming to pass like hours. I have had a seizure disorder for most of my life and I have experienced "missing time" on dozens or perhaps even hundreds of occasions. During a seizure my mind is a blank, then when I'm recovering from one I'm disoriented and for a while I can't tell if a minute or a day has passed.
The way we perceive time can be altered by a number of causes. When experiencing something traumatic or frightening for instance, time seems to slow down, allowing us to evaluate the situation and make quick decisions. Time did not, in fact, slow down, but our perception of it did, most likely brought on by stress, a rise in heart rate and blood pressure, and an increase of adrenalin (plus the old 'fight or flight' instinct thrown in for good measure).
Time can also seem to speed up when we focus our attention on something; reading a good book, playing a cool video game, or even just having a few pints with friends. Again, time did not speed up, but rather, our perception of it was changed.
Relating to cases of so-called abductions, when a person has convinced him/herself that what they is witnessing an actual paranormal event, they will lose track of time by focusing on whatever it is they are actually seeing. When they later try to piece the events together they realize that there is a certain amount of time that they cannot account for. This can be explained by hysterical amnesia, which is basically selective memory loss. In other words, just because those people lost track of time does not mean that they were abducted, then had their memories wiped.
And just to add, now that my sight is almost completely gone, I've personally begun to perceive time differently. What may be a full day to others feels like only half a day to me. I sometimes have trouble sleeping because ten PM feels like four in the afternoon. My days have become longer, yet I can still roughly estimate when an hour has passed.
So back on subject, missing time can easily be explained by altered perception and dissociation. No aliens needed.
Edited for "Missing words" lol
