Creating a door where you want to walk through might work.
This is a old thread 
I seem to have trouble walking through walls and I have tried it many times. The best I have done is getting my hand through the wall. Although one time I had some success, the wall went through me 
I just held my hand infront of the wall and it came towards me and when I was all the way inside the wall it just disappeared. And all the other walls had changed color.
i got stuck in a fence last night…
i was never good at walking through things but anyway the fence and I sort of became one, it sort of melted into me, I had some DCs help me get out of it
i had somewhat better luck with running through a door… it feels really weird.
