Yes. Its very easy to see/hear/smell/feel things that are not really there and begin spiraling down into a deep paranoia. Like, imagine a squirrel makes some noises, and you cant place it but you think you see a dog hiding in the darkness. Or is it a dog? What if its a bobcat, or a rabid raccoon? Suddenly you realize you might not be safe all alone in a forest tripping balls, and you didn't plan for this. Its very easy to slip into chaos without another person there who isnt high, to validate reality and provide a frame of reference for you to compare to. 

What is even worse than this is if what is happening is actually real. What if you lay down to look at the sky/trees and you start hurting all over, because you laid down on an anthill. Even if you managed to get all the ants off of you, you night spend all night feeling them crawl Around you as its dark and you are super sensitive to the possibility you didn't get them all off.

Of what if there was a rabid dog, a pack of dogs, or raccoon, or a literal person who happens to be walking alone at night and finds you? What if you turn and hit a tree and stab your face/eyes? Of get caught in poison ivy? Did you start a campfire? Is it starting to get out if hand and burn the forest around you? Hope you don't lose your balance and fall face first into it, etc..

Yeah, its "unlikely" to happen (and people are always super optimistic and "yeah yeah thats bullshit! That never happens! I would immediately do the correct and responsible thing!" ) but i have found all my well planned plans go to shit and uncommon things easily happen when you take psychedelics and go outside, especially alone.  Sometimes people want to just fuck with you, or they too are high/drunk/etc. without being in a group or with a sober person to step up and see whats "really" happening and take responsibility for the situation (which includes possibly leaving and them driving you home) if you start to have a bad time that bad time can escalate and go on for hours.

Until you have a very "bad trip" its easy to hand wave away how bad things can get because "good trips" are just that: nothing bad happened, real or imagined. Its probably the same reason people who drink get in a car and drive. They only "see how its possible" after they get in a wreck, or kill some people.

Also: definitely do not be alone for Your first time.
