i used to have a returning dream when i was small that i was falling at great speed through a tunnel head downwards or a lot when you are in the underground with a giant escalator which is steep to start with then the center of gravity and angle of it shift and i plummet unless i grab hold of something horrible. luckily didnt have those for many years I did have an injury tho when i was even smaller when i fell from 2 or so floors up downwards and head hit the post box which surprisingly cushioned the wall so i only had a mild concussion i suppose i didnt realise it at that point but that might have been what caused the dreams subconsciously etc.
Been years since i had a dream i could control as well :( im told that people dream less as they grow older has this been true for you? or that dreams get black and white for adults when they are colourfull for kids?
