You actually have access to the Eternity right now. It is a time where no future and no past thoughts exists.
It is that moment, in which no time seems to exists, and you return to the eternity whenever you go to 'sleep'.

Sleeping means turning off something.

1.See: you really can't recall anything what happens with your Body while asleep.

2.If you are used to Daydreaming, then you can use that state to jump into eternity.

3.Total relaxation. Remember ever being at the beach, and wanted to enjoy the warmth of the sun ?
and you suddenly shut off all worries, all thoughts and just let the sun shining on you -> eternity.

4. meditation, you are able, through meditation (which is same as 3) to reach it.

Time cannot hold yourself from where you should be, but you need to take time to get into eternity.

From my PoV atm, there is no Afterlife, because what timed beings call afterlife was life before time begun, and is life after time ends.
But as you can reach eternity now, what meaning does time have ?
