How is it possible to separate from the body? What maintains the connection?
The body and soul are not connected only through the mind. An OBE leads to the separation of the body from the other identifications of the soul, not the body and soul that remain connected. So, considering that the body and ‘astral body' are not linked (no so-called ‘silver cords'), the distance between them is irrelevant.
What would somebody, in physical proximity to a person having an OBE, perceive?
A person in the normal state would see only the physical body of the one who is experiencing and not notice anything unusual. An OBEr could affect though, in a subtle way, the energy of the other person (if s/he can penetrate the rings). So, although it is unlikely that an observer would be aware of the ‘astral body', s/he may recognise an attempt to influence shis energy field. Animals have only one ring and are more open to direct experience. Anecdotal evidence suggests that if the attention is turned towards them, they can sense the presence and the direction of its approximate location. This indicates that not only the perception during an OBE, but also the mental identification through which the self perceives correspond to something objectively real.
How is it possible to have full access to the memory during an OBE?
There are two options here. One is that the range of frequencies is widened, so awareness still has access to the brain processes. The other is that the soul and the rings can temporarily re-create memories without direct connection with the brain.
Why paralysed people, for example, do not have OBEs more frequently?
This would have been merciful, but there is no evidence in this respect. One explanation may be that paralysed people are aware that they are paralysed, and, therefore, their existing construct of reality is a further barrier to such experiences.
How is it possible to remember an OBE after returning to the usual state?
Whatever enters awareness has the potential to be in awareness again (to be remembered) regardless of the source of the original experience. In other words, ‘translation' is not necessary, especially if it is taken into account that constructs are involved in the first place. However, if after the experience one falls into a deep sleep, an associative link may be difficult to establish, and s/he may not remember what happened.
