Bubbles forming and bursting

To me it seems like when one bubble bursts we get in another bubble.
from '95 to '01 we had the dot-com bubble and declined for roughly 2-3 years.
Immediately after the burst burst of the dot-com bubble we were in the housing bubble (2001-2005).
The housing bubble burst 2006 and has been declining ever since.
Now we are in the oil bubble.

My guess on it is that when one bubble bursts people put there money in another bubble until that bursts. Because it is all about getting a higher return.

Let me know what you guys think.
