So when we die do we go in to the 'spirit realm'?
A lot of people who have had NDE's describe leaving their body as a feeling of expanding or spreading out, and the feeling of returning to the body is said to be squeezing into it, contracting, a tight fit. This leads me to think that when one leaves the physical body they become aware of the full range of dimensions which is the feeling of "expanding". Coming back into the body they would have to compress their awareness until they were only aware of three dimensions again.
We know of 3 physical dimensions and 1 time dimension, but there is speculation as to how many physical dimensions there could be and it's pretty well hypothesized that there's a 4th physical dimension. It seems as far as physical dimensions there is likely twelve, but I cannot say for certain.
To better understand the concept of multiple physical dimensions, understanding what beings who experience fewer dimensions can help -
Flatland is a story that attempts to explain such things.
