For me things get real creepy and lonely once it gets dark.
When solo and darkness is falling you really get that feeling of vulnerability.
Night fears largely went away over time, though it is my least favorite part of soloing.
Your biggest friend for night time anxiety is a good set of ear plugs.
Without a fire I quickly start to feel a bit bored, lonely and depressed and sounds in the forest start to make themselves known.
You have to make really good friends with yourself. It can be a long process.
The quotes above are from @Blukanu's thread, Solo—fears and boredom.
Never being a hammocker or one who's slept shelter-less on the ground, a thought popped into my head in re-reading that thread: If I were in a hammock, where I could look all around into the deep, dark woods, would I psychologically feel more hyper-alert, uneasy, vulnerable and fearful than I do within the "protective walls" of my tent.
Ever since childhood, I have been used to going to bed alone. At home, it's just me and usually a book and the walls of my room. Hundreds of times in my van, it's just me and a book and the walls of my van. When canoe camping, it's just me and a book and the walls of the tent. I don't really ever think or worry about what's outside my little "world of walls" unless, perhaps, there is some really unusual noise.
But what if I were in a hammock? And every time and everywhere I looked around I could see creepy darkness, shifting shadows, changing light patters, and . . . maybe . . . some MOVEMENT OVER THERE! Would I feel more uneasy, vulnerable and fearful than I do in my psychologically safe tent wall world.
Hammockers, what say ye?
