I hope that such guidance from an individual who has only recently passed over, and who is in regular contact with this world through his mother, will personalize the situation for many who are unsure what to make of the so-called spirit world.
There's any number of historical accounts about life in the nearest realms of the etheric with most saying similar things in greater or lesser degree. Hearing about life there through Carol though emphasizes that so-called spirits - Mikey in this case - are still very much individuals and still very easily recognizable by their characters and characteristics. Spirits aren't the weird and threatening ghosts and ghouls that many folk associate with the afterlife.
Most importantly - as I see things - Mikey can say how it is for him in respect of any situation. Not general indications about life 'over-there' but how it actually is for him as an individual. Each individual will feel it as an individual and not as a homogeneous entity called 'spirit'. Personal feelings are totally valid even if they're different from those that other (spirit) individuals report because each individual is at a personal level of spiritual progression, a personal level of spiritual understanding.
It's that individuality which makes accounts of life in the etheric so interesting and intriguing yet still confirm the general details given in so may other accounts.
