can be in vacuum

I gathered up my power into a defensive barrier around me, running it through my shield bracelet, and gritted my teeth. My heart pounded against my chest. It was entirely possible that walking through that doorway between worlds would take me to the bottom of a lake of molten lava, or over the edge of a rushing waterfall. There was no way to know until I actually stepped into it.
"I told you so!" Bob chortled.
An electric engine buzzed above me and then abruptly died. Someone made puzzled sounds. Then a slender steel blade slipped through the crack in the door and someone started cutting through the bolts by hand.
I stepped out of the real world and into the Nevernever.
I was braced for whatever would happen. Freezing cold. Searing heat. Crushing depth of water - even utter vacuum. The sphere of force around me was airtight, and would keep me alive even in someplace like outer space, at least for a few moments.
I emerged into the Nevernever, my shields at full strength, my blasting rod ready to unleash hell, as the invisible sphere of force around me slammed into -
- a rather lovely bed of daisies.
My shields mashed them flat. The entire bed, in its little white planter, immediately resembled a pressed-flower collection.
I looked around slowly, my body tight and ready, my senses focused.
I was in a garden.
It looked like an Italian number. Only a minority of the shrubs and flowers were planted in raised beds. The others had been laid out to give the impression that they had grown naturally into the space they occupied. Grassy paths wound through the irregularly shaped garden, twisting and turning this way and that. A hummingbird the size of a silver dollar darted down and tucked its beak into a particularly bright flower, and then vanished again. A bee buzzed by - just a regular old bumblebee, not some giant mutant monster thing.
Don't laugh. I've seen them over there.
I adjusted the shielding spell to allow air to pass through it and took a suspicious, cautious sniff. It might look like a nice place, but for all I knew the atmosphere was laced with chlorine gas.
