I have a more upbeat experience of this. Twins not fully shut down so some of this may range on the fantastical.
Patrick knew about car engines. Don't know how. They mentioned cars I remember in physics at school twice and I liked reading a car magazine occasionally and I sat in a garage where cars were being fixed quite alot. But didn't "learn it" or do any of it.
Then I got a chance to do work experience in a garage. I was working part time at the time anyway. I picked it up relatively quickly. They said go to college, I did in my 30's. I was one of the students other students would ask for help and the tutors would ask me to help others. I aced every exam except gear boxes, Pat said he was never a gear box person.
Patrick has past lives. That's how they view it. The twins. He was many things in past lives. Chronological order is difficult. But he was: a pirate, a highwayman, a footballer, a mechanic, a painter and decorator, - some other stuff but they blocking it now, they said that's enough or it goes back in time to irrelevant stuff.
So if we take "past life" to mean internal life then he did take the internal external.
Also before anything he could hear misfires, and say "it could be the..." And sometimes I didn't even know what I was saying.
Also I remember a conversation in my car with a woman I worked with who Pat says he knew in a past life. Their convo went like this: her "look at that" me "yeah it could be the rings" her "it could be the pistons" me "yeah, he's ###$" She has never studied mechanics but apparently the conversation made sense technically.
In someone's house, a similar thing, they were cleaning. (Pat and the same woman) She said "waters slow out this tap" me "yeah it's the pressure" her "they got the wrong pump" me "yeah or its because of the two taps running" her "ummm" me "they probably fitted the wrong pump to run two taps like that" her "should we tell em" me "no, we're being paid to clean not fix their plumbing problem, it's always like that just ignore it" The guy was downstairs, the next week we got there and he said "I got a plumber in, the last plumber fitted the wrong pump so the water pressure is good now" It was embarrassing because he must of heard us and also how did he not realise his plumbing was bad, he's a man.
So sometimes with things like this I occasionally think "was there past lives?" Because of how Pat can be with some people, not many but occasionally it is like he connects differently. Even when we saw the woman who knew about cars and plumbing other day and cried because she's in a wheelchair now she said "man up" - what woman says that to another woman. Pat has a certain sadness in him that I see in her too. I dunno it's odd.
Anyway inside can come outside. Like nobody had fired a gun but some were better at it than others. Some can sing and some can't. It's odd and it makes it feel like "souls" not fragments of one person, "souls with past lives" But I don't like to go down that train of thought too much because it's not psychologically sound or probably helpful.
Lilly yesterday changed completely. At first she was like a teenager and then the twins said "you're Florence Nightingale rembember" and she suddenly went very older and very sensible and very knowledgeable on basic medical stuff.
But that could be the twins using those things. Like Pat said at some point the twins like parts to "be" stuff and he didn't want to be William Teach so he was Len Davies instead that day - I didn't even know who Len Davies was but he's a footballer. I know who William Teach is because someone was obsessed with female pirates for ages and you have to read alot of pirate stuff before you find stuff about the women that were pirates but I didn't connect it till Pat explained what I'd heard waking up. So they could use the idea of past life to trigger different shades of an alters character. I don't know if that's possible, I dunno.
Anyway inside knowledge can come outside sometimes. But it's easier if you put time and effort into it.
Personally I tried learning Python code briefly because the twins said Beth can code and hack. I thought that's useful in these times, learning code sounds like a good idea. But it was so boring. I dunno if Beth would actually outwardly learn it. It looked really simple but very irksome, not something I would want to spend time doing so I did it for about an hour and didn't do it again. I don't think anyone really wanted me or themselves to actually do that. It's one of those things that sounds interesting but is really dull to me.
So bake stuff, get recipes and bake stuff. That's how to be a good baker
Oh sorry Rose's tips: always cream the butter and the sugar first. Then very slowly add the egg a bit at a time so it doesn't curdle. Always sift the flour. Fold this in do not beat it. The folding gets the air into the cake. If you don't do it in this order in this way your cake isn't so good. The only thing that you don't need to worry about this with is Brownies. But when making Brownies use vegetable oil recipe - a Brownie is not a cake.
I didn't know I could bake incredibly well till Rose did it. Before Rose started doing it I made flat cakes. So again it's possible for internal skills to come out.
I think with Lilly she has very converse past lives or internal lives. One a nurse, one a serial killer, one where she was taken in by Rose and Patrick and is sort of normal - lazy I'd say but basically normal. Different shades of a character of a person, like all people. Lilly to Paul is very sensitive and vulnerable. To herself she's tough. To me she just seems sort of normal but a bit lazy, she could sit around and live a life of shopping and coffees and be content. Doesn't seem particularly sensitive or tough.
The more I know about parts the more complicated it gets, they aren't 2D.
