Hello @aspen27,
I’ve only ever seen scorpions in zoos- I’m sure I’d be also be pretty terrified to see one out and about! 
Megan has given some awesome information and some very helpful guides for decoding potential messages from guides. The only other thing that came to mind was perhaps looking at it from an astrology point of view, as The Scorpion is one of the 12 signs othe Zodiac 
The moon was in Scorpio this past weekend- Friday, Saturday, and Sunday- but has since moved through Sagittarius and into Capricorn where it is currently. You could potentially check the Astro Seek Planet Map to see which if any planets were in Scorpio last night for your location (you can enter your city or zip code at the top of the page for exact location results). And could then check the meaning of the planet(s)- @Cosmic_Curiosity just shared an amazing guide to each of the planets and their meanings 
If the meaning doesn’t become apparent to you, I wouldn’t worry about it. If there is a message from your guide that they want you to see, they will make sure to get it on your radar. Keep your mind open and stay aware for any other potential signs over the coming days. If nothing else appears, then I’d say it’s safe to believe the scorpion either wasn’t a sign from your guides, or that you got the message that was intended for you and no other signs are necessary.
Blessed be!
