Stargate SG-1: Forever in a Day

SINOPSIS

In the middle of a battlefield Daniel and Amonet meet in a tent. Amonet uses her hand device on Daniel, and he passes out. When he awakes Amonet (and Sha're) are dead, their body's stored in the mortuary. Daniel is really depressed and resigns from the Stargate Project, but when he wakes up next morning Sha're is right beside him. All signs in life tell Daniel that Sha're is dead, he even went to her funeral. Yet he keeps seeing her everywhere, in his bathroom, at the SGC, even at her own funeral. Is there something keeping her back from finding peace?
