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?
