I've done it for shorter periods of time, but always wanted to do it longer. I can say I know exactly how you feel, and that if you are feeling the need to do it-don't let anything stop you! This is your soul calling out for replenishment, and if you don't do it, or if you do it incompletely, you will suffer afterwards, depression, an accident, illness, so do it and be careful. If you feel like you should do it for 2 days, be sure to do it for 2 days, if you feel like a week, be sure to do it for a week.
Personally, the things I have done is go walking on my dads land, which is partially wooded, at night in the summer or early fall on a moonlit night, or just take a whole day and go to the woods and do something if it calls to you, or do nothing at all. And I always feel better. But I always go alone, and from the sound of it-you should too.
I neither believe nor doubt it, but do you believe in the possibility of the existence of sasquatch? I have heard many reports lately coming out of Penn.. It's be neet to have an encounter while you're out there.
