Hypothetical Dimensional Merges

Hypothetical Dimensional Merges (HDMs) occur when a hypothetical scenario becomes a reality, causing a merge between different dimensions. 
When an HDM occurs, the hypothesized scenario becomes real, and reality is reshaped to accommodate it. The changes may be subtle or dramatic, depending on the nature of the hypothesized scenario. Some HDMs have resulted in catastrophic events, while others have been relatively benign.
These strange and unpredictable events have been the subject of intense study and speculation by scientists, philosophers, and mystics alike.
== Causes ==
The exact causes of HDMs are still not fully understood. However, there are several theories about what might catalyze them. Some scientists believe that intelligent thought and imagination play a crucial role in creating these phenomena.
Despite the Orb of Prophecy previously being used to bring hypothetical scenarios into reality, these cases are not technically HDMs. 
== Effects ==
The effects of HDMs can be both fascinating and terrifying. They can result in dramatic changes to the physical world, the laws of physics, and even the fabric of space and time. For example, an HDM may cause a previously hypothetical creature to suddenly become real, or it may alter the course of history.
HDMs can also have profound psychological effects on individuals and society as a whole. People may find themselves suddenly living in a world that is vastly different from the one they knew, and they may struggle to adapt to these changes.
