Sensation

I keep having these sort of momentary flash backs. Subtle out of body experiences where I can so vividly remember how it felt to be in a moment as a child. The feel of the sun on my face on a beautiful summer day. The sound of wind whistling through the trees while laying on my back at the park. The feel of the cool, moist sand on my hands while digging tunnels. The weeping willow trees in an open field that made everything feel like it was out of a story book. Sometimes it worries me. Why am I feeling this way? Is this the calm before the storm or should I just bask in the sunlight?
