Whirly swirly portal

Sometimes, with the right resonance, frequency, the barrier between worlds weakens, and a portal opens.
A point of light, then a swirling vortex of color… and finally, a glowing tunnel.
Strange glowing vapors and humming come from the tunnel.
Where does it go? Where does it lead?
I stick my hand in… it feels cold… and warm at the same time.
Dare I look? Peer deep into the void?
Nah. I don’t need that in my life.
I drag the garbage cans over and dump them into the tunnel.
It’ll save me a few bucks off of the trash tax.
