once when i was trapped for weeks by my brain issues, unable to really do anything physically, likely entering loops of dehydration and such that worsened the issues — aside, i recovered from this — i spent a lot of time or energy imagining and 4 dimensional space bent such that a bag contained itself, and could also be carried around.
so you could have this bag where you’d reach in and there would be the bag. i think it basically looked like the surface of a hypertorus with a hole in it, but there were quirks or something it was hard to imagine, especially in my state of mind, but got easier because i tried for so long. it’s not as easy at the moment.
