As far as I know there are different levels of existence that are divided into 9 main dimensions (with smaller sub-levels inbetween) and currently the physical world we live in is the 3rd-dimension. The astral is the 4th (dreams are said to occur here) btw.
The difference between each dimension is unbelievably immense. Imagine a 2-d cartoon living in his little, tiny, level of existence, unknowing of what there is "out there". Now imagine all of a sudden appearing in our realm. He is totally mind-blown as everything has just change for him including a whole new set of rules and physics, he is having feelings and sensations he has never experienced nor could imagine before. Imagine that except going from 3-d to 4-d.
I haven't, nor have I had a legimate OBE yet but lmfao!!!! WTF, I hope you weren't about to project into a playground hahahaha
I don't think the question, "Who are you?" makes a lot of sense to astral beings for names do not matter or it may not have a name. Maybe ask, "What is it do you want to show me?".
Speak telepathically, it's easier ;)
Maybe wear ear plugs to cover the noise?
That's my input, hope it helps.
The most important thing in my opinion is letting go and developing your own experience. I believe meditation can be self-defined. Try not to worry yourself over bothersome thoughts either when meditating, just acknowledge it and continue becoming one with consciousness.
