Seizures
To dream of having an epileptic seizure represents extreme emotional sensitivity or anxiety. Possibly a sign that you are too emotionally invested in situation or dependent on an attachment.
To dream of seeing someone else having an epileptic seizure may represent surprise or shock with someone else's emotional sensitivity or anxiety.
To dream of property being seized by police or the government represents intervention. Feeling powerless to stop someone with more power than you. Waking life situations where you or someone else has to be stopped because they may be going overboard with unhealthy or negative behavior. Feeling that someone with more power than you doesn't want you to do something ever again.
