I have two profound experiences to share with you while recently inhaling salvia.
Now, I've never had much luck hallucinating with drugs (acid, shrooms, dxm..never really hallucinated!)

the first is really simple. while smoking salvia with my girlfriend the poster behind her "came to life" It started screaming, glowing. Quickly, our reality seemed to merge with the reality of the poster. The ceiling of the room turned into a kind of hell. The screaming turned into a roar. The people in the poster where stepping into the room. They wanted us. They were trying to take us with them!!! It was fun. I've attached an image of the poster so you can get a better idea of what it was like.

The second was more profound. I want to know if any of you have had this experience. I'll make it short...what happened was a total merging of dimensions. I really dont know how to put this into words. Dimensions merged. It was like my mind was changing our universe. Its simply beyond words

This was a 10x salvia combination with DXM.
