don't most dreams seem real while you're dreaming them? There are a few lucid dreams where people know they're dreaming and can even take control of the content, but I don't think they're common.
I don't even know about vividness. The ones that seem most vivid to me are the ones I wake up in the middle of. I don't think I remember other ones at all.
Sometimes as im falling asleep in limbo I feel like i’m falling over because i’m laying down but mildly dreaming/ thinking about standing up and it jolts me awake
Many, many times. I wake up shaking. It's horrible. A particular one (the other night) I was walking along a pavement and stepped off a kerb...…………….. it mutated instantly to a huge drop, I scrabble and scramble, but must fall. This sort of falling dream (something I thought was small becomes huge and life-threatening) is far too frequent. I have woken up shouting and screaming in the past. Not nice.
^^^ Addendum. Very, very rarely I have had a flash of a dream which presages/echoes something that has happened/is happening. E.g. the Us spacecraft which went on fire (Nicola McCauliff) I had a 'flash' of people trapped in flames and woke-up shaking - went downstairs to hear the news later. These episodes are (as I said) very, very rare - but very, very clear and real. Quite different from normal dreams.
I’ve had lucid dreams, as in one where I was dreaming that I was stuck in an attic and couldn’t find my out. I thought to myself ‘I’m just dreaming. I can just BE out’, and the dream carried on with me on the roof or something.
