I had a teensy brain injury some years ago and I had lots of 'hallucinations' afterwards - like being able to see someone on the other sofa reading a book - dressed in chunky white jumper, work boots and jeans. I could see them turning pages and crossing and uncrossing their feet - but if I looked at their face, they disappeared. If I looked away, they reappeared.
Also, a little white dog playing in the hall in my peripheral vision - that disappeared if I looked.
Also, I was aware of people walking across the hallway - but they were too quick for me to look fast enough.
My only night time one was using the downstairs loo at 3am to avoid waking anybody, but when I opened the door to go back to bed, I was confronted with a huge, metallic blue tunnel - made of the Mylar metallic balloon-type material that was shimmering - rather like the "O2 Priority - follow the rabbit" adverts.
But I could reach though the material on either side and feel the door frame - a bit like those 1970s laser disco effects. The hole my arms made closed up when I retracted them..
I reached down and could feel the hall carpet - again, the hole closed when I stood up.
I stumbled out in to the hallway inside this shimmering tube/tunnel and followed it upstairs, reaching through the sides to feel the walls on the way, the holes again closing when i pulled my arms in.
In the bedroom there's a large cupboard one side and en-suite on the other so I could still feel both walls until I had to enter to main part of the room - somewhere in front of me is the bed- but I could only see the inside of the tube -I carefully reached forwards and shuffled carefully to where the bed would be, got in and closed my eyes - all back to normal - the tube was gone..
