When a person travels to the astral plane, a common sensation is a feeling of slipperiness. This is the sensation of the spirit body as it progresses to the astral level. This feeling is not the physical sensations, but the analogy of your physical body being immersed in water and that feeling of being slippery. This is how the mind translates what is happening when the energy body passes through the physical world to the astral levels.
The sensation of being weightless is a similar sensation to swimming underwater, so this is how the mind will translate the sensation of the astral travel experience. The feelings and sensations are similar to what is experienced in the medium of water; feeling weightless. This does not mean the astral is under water. It just means this is how the mind is translating the sensation of the experience.
Poking Head through Water
Some people will describe a sensation as if they are in water and are now able to poke their head through the water to another dimension. This description is a way to interpret and accept how there is a different medium between the levels.
Speckles of Light
You will have different sensations stand out in different times astral travel experiences. For example, when you start to visit and interact with other souls, you may have a memory of seeing speckles of light. This is the experience of seeing other fragments (souls) and their energy of radiating light.
Travel Experiences without Sensations
There will be other times you visit the astral plane and you won’t have these sensations of weightlessness, slipperiness, or speckles of light. This is because the mind has moved on to focus on other aspects of the astral travel location and is finding a way to process this new data.
You obtain information on the astral level much like a computer does; in large batches very quickly. It usually is mostly raw data. It usually takes a period of time for your mind to first comprehend and then visualize this data. As the energy body receives the data, there is no visualization that accompanies it. Simply, the way knowledge is passed is by the knowing process. The mental mind, however, cannot put this to use unless it places some reference to it in the physical plane. So it creates visualizations and experiences that allow the information to become useful.
Your Dreams will Start to Broaden
This is why when you travel to the astral plane, your dreams will start to broaden. This is often you the mind will process and interpret the information and data it has collected. It will put the data together in images and metaphors as a way for you to interpret these different experiences.
Your dreams will broaden as your travel experience increases. You will start to have new insights, wisdom, and understanding of both the past and future. All of these will increase through your dreams. The mental mind accepts information, especially details better in this fashion.
So as you start to travel to the astral plane, you will experience a progression of sensations. First, you will probably have a sensation of slipperiness, or poking your head through water. Next will probably be a sensation of being weightless. As you start to expand and meet other souls on the astral, you most likely will recall speckles or flickers of light. Next, your dreams will become more intense and broaden. Eventually, you may be able to recall the experiences or retrieve the knowledge and insight directly.
