I have read some of Jacques Vallee writings regarding the UFO phenomena..."having experienced this, what do you think about though alien abduction reports where people report being paralysed or zapped by aliens in the middle of the night?"

I think he is on to something when referring to parallel worlds, the UFO phenomena and associated experiences being in origin from another dimension. I would modify his thesis and suggest that these "dimensions" are accessible via consciousness only. Sometimes our state of consciousness can "shift" perception, this can be felt when having Out of Body experience, using certain "hallucinogenic" substances that can in a sense, lift the veil of our limited perception (limited by the physical senses and the physical plane of existence to which it grounds us). This shift in perception can account for time gaps, memory loss, etc.. experiences typically felt by abductees.
Yet to me consciousness is existing, and existing is the act of becoming aware, and being aware is the act of perception, and perception is the act of using our senses, and these senses can have input from a variety of sources. Some of these sources are purely psychological, yes, but others have been shown not to be, as when a group of people have a collective abduction experiences as with the Case of Betty and Barney Hill.. http://en.wikipedia.org/wiki/Betty_and_ ... _abduction and countless others.
If some of these experiences are happening collectively, then we must postulate that consciousness does indeed have collective properties. If this is so, you can already imagine the endless implications. It could very well be that these experiences in consciousness (abductions), are a state of a collective reality of those called "the aliens", and we humans become receptive to these states that allow them to exist. In a sense, we create them because we can, and the aliens create us because they can. This might be sufficient to trigger subjective experiences that can at times manifest into "real" collective physical experiences.
Before I go on let me talk a bit more on subjective reality. This means that You are the consciousness within which everything exists, the perception of time/space and ALL experience. In a subjective reality you identify with the container in which the whole simulation occurs and not simply by the physical senses.
In the attempt to understand something so complex by consciousness that happens to be human, different interpretations is not only rational but should be expected. The complexities of subjective reality are too vast to reliably decode small glimpses of information. The UFO abduction phenomena in essence is the effect of decoding these small glimpses of information by the limitations of our current sate of consciousness. To me it is more likely that these aliens are "in us", or are part of us, as they can exist outside time/space as we can exist out of space/time at least for brief moments while out of body, or do I dare suggest much longer?
This is what I refer to when saying existing in other dimensions, or I would prefer to say, existing in other states of being. I think consciousness has magnificent properties only starting to become unlocked in resent times.
Personal research (and/or personal realization) is the most valuable and useful research and in my opinion it is the only thing that counts towards our evolution. We will be manipulated, lied, and indoctrinated by a variety of "belief systems", let this not be a deterrent to seek "YOUR OWN TRUTH", and not fall into the trap of belief in the opposite of the "belief systems", simply because you cannot agree with it. There is no left or right, best or worst belief, as it is infinite. Find your path by never stopping learning. Always question everything, everything can be viewed as a learning experience, you can then use your findings in the "Astral Realms" (or what i prefer to call other states of being) to see how it resonates with your inner you. One thing will then lead to another, the path of self discovery.
Have a great day!
