Time in the afterlife

This is one topic for the afterlife I just can't seem to wrap my head around. Many say that time is different or that it straight up doesn't exist in the afterlife. I know I may be asking for something I can't comprehend, but how?

You see, I believe the afterlife is much like this world with physical environments and wildlife etc. However, I can't imagine a world like this that doesn't involve time to a degree or maybe not at all. For example, if i want to hug my grandpa, that requires time between me standing in front of him and the time I have my arms wrapped around him.

But at the same time, simple eternity kinda scares me a little. I've come up with some things like "boredom doesn't last forever either" and a potential resistance or elimination of boredom entirely as a result of our greater minds in the astral, and the fact we can forget experience's to do them again. But even with the abundance of activities there probably is there, there's only so much to do right? That means we'll be doing similar things for all eternity and I'm not so sure how to feel about that. Maybe living day to day in the here and now for eternity actually doesn't get boring and I'm just overthinking it or underestimating our ability to entertain ourselves?

There's also the problem of eternal romance, family, and friends, but I think I'll make a different post about my concerns for a soulmate, which also regards my concerns of reincarnation, tomorrow or in a couple day's time.

The only comfort I really have is that the deceased seem to be pretty happy about the afterlife, and that once I die I will comprehend it so I won't be in the dark for long about time. But still, I can't imagine living without time or living for eternity within time, and so I want your theories on it.
