Dreaming of a Whole Day
If a dream clearly spans a whole day, it serves as a reminder to the dreamer to be mindful of time in certain activities and not to waste it.
Time does not have a true meaning in dreams. If the dreamer notices that time can be measured in the dream, it indicates that they are contemplating a question about how long their life can continue.
The expression "a day feels like a lifetime" makes the dreamer aware that, on a spiritual level, time is not an important quantity.
