Did the apostles wrongly conclude “resurrection” from “we saw Jesus”?

Introduction

Question: Could it not be the case that the Apostles, Paul, Mary, and so forth all assumed Jesus resurrected after simply, but mistakenly, believing they saw him or visited with him after his crucifixion?

Relevance: This questions plays a role in other questions, notably:
• Was Jesus's tomb empty? After all, one argument is that the Apostles, Paul, Mary, etc. proclaimed that “Jesus has been eschatologically resurrected from the dead!” But if they concluded this simply from seeing Jesus, and mistakenly concluding he rose, then we no longer have this argument for the empty tomb.

“No, after all…

They inevitably checked Jesus's corpse

If Jesus did not actually resurrect, then he/she/they (the apostles etc.) soon would have visually seen his remaining corpse.¹ This is relevant because they did not see a remaining corpse of Jesus's, but they continued believing Jesus resurrected.

We know the AD 30 Jerusalem church would have visually seen Jesus's remaining corpse eventually because they were saying “Jesus' tomb is empty!”. Several potential converts would have wanted to check, as would Jewish enemies.

Visits from the dead aren't seen as resurrections

For Jews like the Apostles (and others), mere ostensible visits from a dead person would not be interpreted as a resurrection appearance or suggest that a resurrection had occurred. (After all, a resurrection is a very particular thing in Jewish thought, and other categories of interpretation would much sooner present themselves[Forthcoming]. Something convinced them that this was not a ghost, hallucination, etc.)¹.

• Markus Bockmuehl: “[Regarding Jesus's ‘apparitions, empty tomb, and apotheoses’] The ancients knew full well that ‘a ghost does not have flesh and bones’ (Luke 24:39) and does not eat or drink, but a resuscitated body might easily have and do all those things. And yet, neither of these perfectly familiar and acceptable categories is invoked by any of the diverse New Testament witnesses. [“Resurrection”, The Cambridge Companion to Jesus (Cambridge, 2001), 112.]
• Dale Allison (NT professor at Princeton): “If there was no reason to believe that his solid body had returned to life, no one would have thought him, against expectation, resurrected from the dead. Certainly visions of or perceived encounters with a postmortem Jesus would not by themselves, have supplied such reason.” [Resurrecting Jesus (Continuum Int., 2005), 324-325.]
• N.T. Wright (NT & Early Christianity professor at St. Andrews): “Everybody knew about ghosts, spirits, visions, hallucinations, and so on. Most people in the ancient world believed in some such things. They were quite clear that that wasn't what they meant by resurrection.” [Surprised by Hope (HarperOne, 2008), 36]

The apostles didn't hallucinate Jesus
