Very suspicious activity.
Grant ONCE AGAIN needs to stop the tape (& for how long we do not know) so he can change for bed.
CHANGE OFF CAMERA. CHANGE IN THE BATHROOM.
During analysis we see his bed sheets are pulled off...or are they?
There is definitely a "block," of some kind TRIANGULAR in shape between his feet that is pulled/slid under the covers thus causing them to "appear," to be pulled.
J shows (some) honesty not claiming this to be paranormal as Steve & Grant do during analysis.
However, fans still see this clip as one of of their most popular paranormal moments.
