In this video this is described very clearly.

I say that this is the relationship between a DZ (fraternal) womb twin survivor and an MZ ( identical) womb twin survivor.
The doctor in the video says: " This is replicating the difficult relationship you had when you were a child." What rubbish.
1. If you have/had parents who "didn't understand you", for example, its not the fact that they are/were so different from you that made/makes you feel empty inside - you were always going to feel empty anyway, because that is how most all womb twin survivors feel.
2. If you are/were not able to make contact with your parents at that deep, empathetic level you crave so much, its not because they didnt/dont love you or care about you, or cant/cpuldnt be bothered to try, its probably your own fear of intimacy and invasion that made/makes you stand off.
That's not their fault. Never.
Time to reconsider how much your parents, be they with you today or not, ever loved you in the best way they knew how.
Philip Larkin has been a guest on this blog before, not because he is right about parents, but because he is absolutely wrong. He died in 1985 a lonely and bitter man because he never understood why he was born with a big hole inside him that nothing in this life was ever going to fill - not even the most loving and doting parent could ever fill that emptiness. (Yes, he was almost certainly a womb twin survivor, in my view, but very few people knew about them before the 1980s)
"This Be The Verse" by Philip Larkin
They fuck you up, your mum and dad.
They may not mean to, but they do.
They fill you with the faults they had
And add some extra, just for you.
But they were fucked up in their turn
By fools in old-style hats and coats,
Who half the time were soppy-stern
And half at one another's throats.
Man hands on misery to man.
It deepens like a coastal shelf.
Get out as early as you can,
And don't have any kids yourself.
They take the rap, your Mum and Dad-
They do not mean to, but they do.
They fill up with the faults you had
And take the blame - for love of you.
But they were carried in their turn
By folks with quite a different brain,
And half the time tried to be firm
And half the time took on your pain.
Child hands on misery to Mum
And lets Dad carry all the shit.
Then he or she is innocent:
And that's about the size of it..
