Fair enough, but can you ask anything but "Are tulpae real?" As you already know i do not have any answer.
Here's the problem then:
Does it matter at all what questions are asked and what the answers are? I can offer to answer any questions you may have regarding what Deadpool was doing during the Secret Wars, but that question/answer session would be nothing more than storytelling or fan fiction. If we talk about tulpa without any regards for whether they possess an objective existence or not, then your answers will be just as meaningful as anyone else's answers. Any contradiction with objective reality that comes up can be easily dismissed with 'well we don't know if it's real'. Do tulpae speak Latin fluently? Sure, why the hell not - we can't find any examples of tulpae speaking Latin, but, well, we don't know if tulpae are real so whatever. Can lizards create a tulpa? No, tulpa require an originating sentience. Why do they require an originating sentience? Well, let's just say
they do. It's not like there is an objective reality regarding tulpae that we can compare that answer against to determine if it is even in the same ballpark, city, state, country, or planet as 'correct'.
I don't really have a problem with storytelling. It's pretty fun; and frankly if anyone wants to have a back-and-forth talking about what Deadpool was doing during the Secret Wars, or what the characteristics are of a talking horse named Ed are, or what the properties of Adamantium are, or if changing the coordinates by 3.6deg on a Stargate would be detrimental for travel or not, we can do that. It'd be fun, but it would be nothing more than making sh*t up for the sake of storytelling.
If you want to try out some 'What if...' scenarios under the assumption
that tulpae are real, that's all good and well, but why would you do such a thing? One reason I can think of doing such a thing is to determine if, conceptually, tulpae are at least compatible with objective reality. But that is treading into the water of asking 'Are tulpae real', which apparently isn't something you're interested in figuring out.
