Is it reasonable to have an invisible friend whom you have never seen?

[Jack Ryan]

...and yet you talk to this invisible friend several times a day even though the friend has never talked back to you?

[JW Insider]

It's not like an invisible friend is going to tell you to kill someone.

Oh wait, are we talking about Abraham?

Sometimes during the day I talk to myself, does it count as a friend? ?

Although my comment is different from what the question asks  since I am not invisible and I reply myself back ?

[Guest Nicole]

And if I preach to myself or to my invisible friend does it count to report it at the end of the month?
