You consciously designed and have an out of body experience in real time if your chakras inserted into the astral body enough etheric matter. The body experiences the reality is perceived as objective and realistic, and time is normal. Here are some interesting details about astral projection.
During sleep, the energy body double, also known as the etheric body or vitality of the body, including to be filled. It expands and opens in order to accumulate and conserve energy. Duplicate it can only do so during sleep. Chakras force fed in the form of etheric matter into energy the body. During the process of filling the etheric double astral body separates and is included in the astral dimension where it can create and experience dreams. To perform something like this requires a great strength of mind, practice and familiarity.
Astral projection occurs when the astral body is projected into the astral dimension, where things are different than in the real world. Time is distorted and extended, ie. one hour in the astral can be like a few minutes in the physical world, depending on the part of the astral you are in. Reality is fluid and changeable.
Many astral travelers lose consciousness before they leave the physical body and regain consciousness in the astral dimension. You become aware after separation from the physical body only when you are in the astral dimension. If you miss the conscious exit from the physical body, you have a lucid dream is not astral projection, since you have become aware after separation.
To conclude, after the physical body has fallen asleep, the astral body is projected into the physical world. Once the etheric body is expanded, the astral body floats free above the physical body or within the influence of the expanded etheric body. Within this field, known as cord activity range, the astral body is held close to the physical world because it is within the field of etheric matter.
When you project the astral body close to the physical world you do not have a body as such. But the mind can not accept this fact, but it provides a body of thought forms made of ethereal matter. If you try to look at your body such as your arms, you will see that look pale and wonder for a few seconds, start to melt as ice next to the fire.
This melting effect only occurs when you intentionally try to look at a part of the body or when consciously trying to create something.
