Were Dany’s undying visions caused by Shade of the evening?

[BaelorTheByzantine]

Before Dany goes into the house of the undying, she drinks shade of the evening. Inside she sees visions.

In The Forsaken, Euron forces Aeron to drink shade of the evening and he has visions.

While Aeron’s visions seemed more like hallucinations/dreams, Dany actually walks past physical doors that act like windows to the visions. Not sure if this is because something else magical is going on or what.
