How can I go back to enjoying toys as an adult?

Okay so long story short and I’m hoping that it’s okay for me to post this, but here goes;

I’m 37 with high functioning autism or Aspergers. Last year I got a Playmobil ambulance for my niece as a home welcoming gift or late Christmas present and myself a collectible Playmobil item for myself.

From that moment on: I’ve been hooked on getting Playmobil for myself and even got some of the stuff I used to have and wanted as a kid. There’s some items I bought which I share with my niece who loves Playmobil as much as I do, and some for me and my nephew when he gets a little older as he’s still only two.

Even went as far as breaking my tradition of getting something for my model railway last Christmas and my birthday this year with Playmobil. 

Yet I want to go back to being my eight year old self again because of what I have and can get online and more. But yet the second I get some out…I don’t know what to do. Apart from having them on the floor and in a scene, that’s all I can get too even though I want to play.

The child in me would be playing with everything from fire engines and rescues to police detectives and cops and robbers with other things including shops and the like. Even used to do male and female voices in American accents with a bit of Brit lingo like calling the fire chief governor or guv. 

I don’t know what could be stopping me from myself. Or how I can break the barriers of my mind that are stopping me.

I’m not sure if anyone else has had similar experiences or ways to overcome such barriers.
