Julius Caesar: The bloody fountain?

In the play Julius Caesar I found something very weird.
After Calpurnia interprets the sights of the watchmen's as a sign for him to not leave the house, Caesar creates an image out of nowhere of a fountain with his blood in it. Why would he do this? And once he does, he tells Decius about this imaginary imagery.
I'm wondering if Shakespeare made a mistake and forgot to put in more pretext that may suggest the bloody fountain was from another conversation between him and Calpurnia BUT, based on the scene this all happens in, it is clear that Calpurnia and Caesar do not spend much time together, nor have they in a very long time.
BUT, this could also have been done on purpose because as we all know, every word of shakespeare counts.
I was hoping this question could be answered.
Does it suggest that Caesar knew of his death, or wanted it to occur? Maybe he wanted a reason for someone to trick him to go to the Capitol and die?
Let me know your thoughts, thank you!!

He didn't create a bloody fountain, but a statue that pour forth like a bloody fountain:

She dreamt to-night she saw my statua,
Which, like a fountain with an hundred spouts,
Did run pure blood: and many lusty Romans
Came smiling, and did bathe their hands in it:

This is one of those moments in which Shakespeare reminds us that we are watching a play of the historical event, by gifting Caesar with the knowledge of what is about to happen (he will be stabbed all over his body and the people come rushing forth).

One of the key questions of this play is how much does Caesar know? We are very removed form him as a character and cannot really tell when he is feigning ignorance or if he is just ignorant. When he dismisses Calpurnia's visions and goes with Decius, does he believe Decius over Calpurnia, or does he know, as we do, that he will in fact be stabbed?

He is certainly not a trusting man, and so he changes Calpurnia's visions into one that more squarely places blame on the Roman people (and the Senate) to show his distrust - but backtracks when Decius presents an alternative to the vision. But again, how sincere is he being?

But how does this squarely place blame on the Roman people and the senate?
Maybe he created this imagery to show how self absorbed he is? He uses a statue, which shows he sees himself highly, but why he chooses to have blood spouting from the statue is unknown to me.

Thanks for replying though, I appreciate it :)

You could be right in that the statue could reflect self-absorbed nature.

The blood coming from all points reflects the realty that on March 15, 44BC Julius Caesar was stabbed all over his body by members of the Senate.
