Exploring the actual world is debatable, as your subconscious works more symbolically than literally.
Meeting with spirits and ancestors is a matter of belief, and cannot be factually proven or disproven.
Dream walking, depending on interpretation, is once again a matter of belief rather than fact.
As for the last item, there are some people who claim to have done this, and ESP continues to be a studied field in the scientific community. It does not get a lot of public attention, but things continue to happen which baffle scientists.
All of those things are possible in the astral realm. You are not limited by logical laws and realty. You can also take on other forms, kind of like shape shifting.
Sounds like role playing to me. These things are only possible in your imagination. It isn't real. No matter how you wish it were for whatever reason. Dream away though if it gives you a reason to get out of bed.
Even though they are only possible in your imagination, astral projection is fueled by imagination. There is no limit to anything you can do, as long as you can imagine it.
1. "Time travel" there are occasions a spirit will send messages via memory or images, it can appear like time traveling if thats what you would call it. Other than that not really sure
2. Yes
3. Not fun to meet old family if you are having relations with a ghost
4. If you mean entering people's dreams...sometimes its just not worth it
5. Some people are kind of jacked up, avoid them if you can
Time travel can be a thing if you understand that you aren't going to actually change anything from the past and that you wouldn't be physically affected at all. It's not usually called time travel, but what I associate it with is a form of trance where one visits the energies of a different time and potentially a different place as well. For example, I experience the US in the 1900's as well as France in the 1700's. I call it time travel because it's spiritually going to a different place much like Pathwalking has the effect of walking to a specific spiritual realm (I also call it that because it is the closest thing I have to express what I feel it is, regardless of how silly it may seem to those who would jump to conclusions about what I believe).
Exploring the actual world is something akin to Out of Body Experiences and otherwise what I understand to be Etheric Projection. The Etheric planes are adjacent to the Physical plane and any time you project to a physical place, this is where it would be happening (when using this term for cosmological models in understanding reality). Etheric Projection tends to be harder, in my experience, for those who are not attuned to it already because I understand Etheric energy to be more dense and "solid" than Astral (Cosmic) energy. It's like how Water is more dense than Air.
If you were to start exploring the physicall world spiritually, I would look up things like Pathwalking, Bi-Location, Remote Viewing, and the like. There will be people who encompass Etheric and Astral planes as "the astral realm" or something akin to a singular reference to sublte planes. It's just as capable of being as valid as the viewpoint I present, but I just find it easier to differentiate the two.
Spirit work and ancestral work are both within the reasonable realm of potential validity, though the experiences will be entirely personal to you as we all interpret even the same thing differently (by proxy of our brains are all different from one another). There are different traditions and ideas to help set up an initial framework and then you can figure out where to go to from there.
The thing about Dreamwalking is that, while I personally believe it to be real, I have no personal way of verifying whether or not I was successful unless I got feedback from a partner. While it's possible to set something like that up, I just haven't done it and I've not read about instances where people have (in-depth, anyway). The same goes for spiritual communication. You don't know unless you're practicing with a partner or it just kind of happens.
This person is likely talking about spiritually exploring the physical world. It's typically what is referred to when we say "in real life" and things along those lines.
1. Time travel Ill give that a NO, you may go into a meditative state and if you're good you might be able to travel back, but in real world you did not.
2. Exploring the actual world Ill say maybe, there have been quite a bit of exploring on this subject, I believe you would have to be very open, and be able to easily get to that vibration, it would take a lot of practice, and patients on your part.
3. Meet with spirits and old family ill give this a big yes, if you can open, or are a medium with the control that you would need.
4. Dream walking Ill say no, unless you are talking about sleep walking. Ive heard people claim this, but I don't think it can be done, your subconscious controls your dreams, and it's like your fingerprint, not shared with others, so I don't see how that can happen.
5. Communicating with other people who are projecting. Ill say No I don't think this can be physically done when you are in that state.
