Neat dream
I believe the interpretation for your dream is as follows:
The path is life, the darkness you see when you try to look whats in the distance represents that no one truly knows what tomorrow holds. The the unreal repeating unreal trees represents the unending problems in life that don't directly effect you or slow you down. The red sky, the rain the chilled unseen mist all represents something nagging at you. You running is your way of dealing with life. The tiredness in your hips and you slowing reflects your lack desire/ability to continue with your life is a present. The nets coming up and your anxiety about stopping represent that if you stop you will pass into an oblivion, abyss, nothingness . See the house in the distance repesents the you are looking for a refuge. The totem represents some type of gatekeeper/guardian spirit that keeps the refuge from being consumed by the abyss and problems of life. The portal represents you entering the refuge and you no longer fear being consumed by the abyss. The cliff(being no more path) and the fact you stop running represents you can finally end your life in peace.
That being said I recommend you find what ever this refuge is and the protection it offers.
