in vision saw 3 connecting protection barriers and they were beautifully made and scary at the same time, complex design, I first watched them to then slip right through, first one, then the second and I stop at the third. They were all diffirent and one more complex than the other.

Should I be able to do so using mind's eye?

By the time I got to the third I asked to see the building instead, wanted to know where I was, and then I got too tired and could not hold my concentration and came out of the state. No astral body used.

Don't know if this was a dream or not but did not feel like it.
