Welcome Yann,
Yes, you are right. Put simply, whatever existence you make yourself fit for, that existence you will attain. Not necessarily sooner; could be later, depending on whatever abhisankharas (‘will’ plus emotional attachment) are strongest at that particular moment.
In my case as well, Buddhadhamma is an extension of how I had conceived Reality in the main. Only, now the whole plan lay before me.
Yes, DO read the posts. You will find the details there. The Forum will prove of value as well.
