Yep, me too...the whole concept of being unable to return home...even though it was Kansas...freeked me out as a little twerp.
I was telling my wife this and she laughed and said the Wizard of Oz scared the heck out of her too.
When I first saw TWoO on TV, at age 4, the Wicked Witch of the West scared me so much that I scuttled off and hid under my bed when she disappeared in her cloud of sulphur in Munchkinland; I still can’t watch the “melting” scene to this day.
